ShareX Scrolling Capture Cuts Off the Page: How to Fix Missing Sections

A ShareX scrolling capture can appear to run normally yet produce an image with the top, bottom, middle, sidebar, or another section missing. It may also duplicate a sticky header, repeat content, or join two page segments at the wrong boundary. This usually means the capture succeeded but the stitching process could not find stable, overlapping visual content between frames. Moving page elements, sticky navigation, capture timing, display scaling, browser zoom, lazy loading, and incorrect crop boundaries are the most likely causes.

The troubleshooting steps below focus specifically on incomplete stitched output. If ShareX cannot begin a scrolling capture at all, that is a different problem involving window selection, permissions, hotkeys, or application compatibility. Here, the goal is to make the page visually stable enough for ShareX to capture and join every section in the correct order.

1. Confirm the Symptom and Reproduce It With a Simple Test

Before changing several settings, identify exactly what is wrong with the final image. Open the captured result at full size and compare it with the live page. Look for a clean cutoff, an unexpected jump, a repeated block, or content that appears in the wrong position.

1.1 Identify the type of missing content

Different output patterns suggest different causes:

• A missing bottom section often indicates that scrolling stopped early or the page loaded more content after capture ended.
• A missing middle section usually points to a failed stitch boundary or a large page element changing between frames.
• A repeated header commonly comes from sticky navigation remaining fixed while the document moves underneath it.
• A missing sidebar may mean the sidebar scrolls independently or collapses at the current browser width.
• A missing top section can result from the selected capture region starting below the desired content or from cropping during processing.
• A duplicated paragraph or image usually means ShareX matched two similar-looking areas at the wrong boundary.

Record which pattern you see. That observation helps you choose a targeted fix instead of changing unrelated options.

1.2 Test a shorter and simpler page

Open a short article or settings page that fits within two or three scroll movements. Choose a page without video, animated banners, floating chat buttons, or continuously loading content. Run the same ShareX scrolling capture workflow.

If the short page is complete, ShareX is capable of capturing and stitching in the current browser. The original page is probably introducing movement, unusual scrolling behavior, or too much content. Stop investigating permissions, uploads, audio, and screen recording settings because they do not explain a successful but incomplete stitched image.

If the simple page also loses sections, focus on the scrolling capture settings, browser zoom, Windows scaling, capture region, and stitch boundaries.

1.3 Repeat the same page twice

Capture the problem page twice without changing anything. If the missing area moves between attempts, dynamic content or timing is the likely cause. If the cutoff occurs in exactly the same place, inspect that location for a sticky element, embedded frame, loading transition, internal scroll container, or abrupt visual change.

Success at this stage means you can reproduce the problem and describe its pattern. Once you know whether the failure is consistent or variable, stop repeating identical tests and move to the relevant fixes.

2. Check the ShareX Settings Directly Related to This Problem

ShareX creates a long screenshot by capturing overlapping views as a window scrolls and then combining those views. The exact options available can vary with the selected scrolling capture method and current ShareX release, but the important controls concern the capture region, scrolling behavior, timing, and image combination.

2.1 Select only the stable page viewport

Start the scrolling capture and select the browser's document area rather than the entire browser window. Exclude browser tabs, the address bar, bookmarks, download shelves, and other interface areas that do not scroll with the page.

If a page has a fixed left navigation panel or floating right sidebar, try selecting only the main article column. A separately scrolling sidebar cannot always be captured correctly as part of the main document because it moves independently or remains fixed while the article scrolls.

Success looks like a final image containing one continuous content column with no missing joins. If that works, keep the narrower region and capture the sidebar separately if needed.

2.2 Slow the scroll and allow the page to settle

Fast scrolling can capture a frame while text, images, or layout elements are still moving. Increase any available delay between scroll actions or reduce the scrolling speed. The aim is to let the browser finish painting each view before ShareX records it.

This matters on image-heavy pages, complex web applications, remote desktops, and systems under high CPU or memory load. Close unnecessary applications if the browser visibly stutters, but do not treat general performance tuning as the first fix when the page itself remains stable.

After changing timing, capture the same page again. Success means the previously missing boundary is now continuous and every image appears once. When one timing adjustment produces a complete result, stop increasing delays because longer capture times provide no additional benefit.

2.3 Review automatic scrolling behavior

Watch the page during capture. It should move in consistent steps within the selected content area. If the whole browser does not scroll, place the pointer over the main page before starting. Some sites contain internal panels that intercept the mouse wheel, causing ShareX to scroll a comment box, menu, map, or sidebar instead of the document.

Also check whether the capture reaches the actual bottom. Cookie banners, modal windows, and chat widgets can intercept input or cover the page while the process continues. Dismiss these elements before capturing.

2.4 Inspect crop and stitch boundaries

A crop that removes too much overlap can make two valid frames impossible to join. Conversely, a very broad region containing repeated or fixed elements can lead the stitcher to match the wrong areas. Reselect the region with enough ordinary page content visible, such as paragraphs, images, and headings that change as the page moves.

If the result consistently jumps at one boundary, compare the content immediately above and below the jump. Repeated card layouts, identical product rows, code blocks, or large blank spaces provide weak visual landmarks. Starting the capture slightly higher or lower may give ShareX a more distinctive overlap.

3. Check Windows, Display, Browser, and Page Factors

Incomplete scrolling screenshots are primarily visual capture problems. Display settings and browser behavior matter because they affect coordinates, rendering, and overlap. Audio and network settings generally do not affect stitching, except that a slow network can delay page content and cause the layout to change during capture.

3.1 Test browser zoom and Windows scaling

Set the browser zoom to 100 percent and retry. Nonstandard zoom is often supported, but it can alter element dimensions, trigger responsive layouts, or create fractional pixel positions that make repeated frames harder to align.

Next, note the Windows display scale under Display settings. You do not need to permanently change a comfortable scaling level. For diagnosis, test on one monitor and keep the browser entirely on that display. If you use monitors with different scaling percentages, avoid placing the browser across both screens.

If necessary, temporarily test a common scale such as 100 percent, sign out or restart the affected application when Windows requests it, and repeat the capture. Success means the page stitches correctly at one consistent combination of zoom and scaling. At that point, preserve that combination for long captures rather than changing several display settings at once.

3.2 Disable or remove moving page elements

Anything that changes position or size during capture can disrupt frame matching. Common examples include:

• Sticky headers that shrink after the first scroll
• Floating social-sharing bars
• Chat launchers and notification popups
• Animated advertisements and carousels
• Auto-playing video
• Expanding table-of-contents panels
• Cookie notices and newsletter overlays
• Scroll progress indicators

Close dismissible elements before starting. Pause video and animation where possible. Reader mode or a print-friendly page can provide a stable alternative when the original layout is highly dynamic. Browser developer tools can hide fixed elements, but most users do not need them. Selecting a narrower capture area is usually easier.

Success looks like every content block appearing once in the correct order. If the only remaining issue is a repeated fixed header, manual cropping is often more efficient than continuing to adjust capture settings.

3.3 Handle sticky headers and floating sidebars

A sticky header occupies the same screen position in every frame. ShareX may include it repeatedly or use it as a misleading match point. If the header can be collapsed, hidden, or excluded from the selected region, do so.

For a floating sidebar, determine whether it is fixed or independently scrollable. Capture the article and sidebar separately when they do not move as one document. Trying to preserve two different scrolling behaviors in a single stitched image can produce missing or repeated sections even when ShareX operates correctly.

Manual cropping is appropriate when the page content is complete and only duplicate header strips remain. Use the ShareX image editor or another editor to remove repeated header segments. Do not keep changing capture timing if the underlying article is already intact.

3.4 Load lazy images before starting

Many sites load images, embeds, and recommendations only when they approach the viewport. These additions can increase the document height and push existing content downward while ShareX is capturing. Slowly scroll to the bottom of the page once, wait for images to load, and then return to the top before beginning the capture.

For a long page, pause at sections containing image galleries, embedded posts, or videos. Confirm that placeholders have been replaced by actual content. A stable scrollbar length is a useful sign that the page has finished expanding.

Success means images no longer appear blank and the bottom of the page remains in the same position throughout capture.

3.5 Treat infinite scroll as a special case

An infinite-scrolling feed has no fixed bottom because more items load as you approach the end. A single scrolling capture may stop before new content arrives, continue indefinitely, or stitch repeated feed cards incorrectly.

Decide on a practical endpoint. Load the desired number of items first, then capture a limited range. If the site continues modifying earlier items or recycling feed elements, take several shorter captures and combine or store them separately. ShareX not working on an endless feed does not necessarily indicate a program fault. The page may not provide a stable document to capture.

4. Run a Clean Temporary Test With Minimal ShareX Settings

A clean test separates the capture problem from editing, uploading, naming, and automation tasks. It does not require deleting your normal ShareX configuration.

4.1 Use a capture-only workflow

1. Open a short, static page in a regular browser window.
2. Set browser zoom to 100 percent.
3. Keep the window on one monitor.
4. Dismiss overlays and wait for images to load.
5. Start a scrolling capture from the ShareX interface rather than a custom hotkey chain.
6. Select only the document viewport.
7. Save or inspect the captured image before uploading or editing it.

Temporarily avoid after-capture effects, automatic resizing, complex image actions, and destination uploads. These tasks normally occur after stitching, but removing them makes it easier to identify whether the original output was already incomplete.

If the clean capture is correct, restore workflow actions one at a time. Stop when the problem returns. Check whether an image effect, crop operation, resize action, or editor step is altering the completed screenshot.

4.2 Compare a full-page test with segmented captures

If a long page still fails, capture its top half and bottom half separately. Overlap the two captures by at least one visible section. If both shorter images are complete, the page length, memory demand, changing layout, or accumulation of stitching errors is likely responsible.

Using several reliable captures is preferable to forcing one extremely long image. It also makes the result easier to edit, share, and review at readable resolution.

5. Check Task History, Logs, and Recent Workflow Output

Task history helps determine whether the correct image was saved, edited, or uploaded. Open the recent ShareX task or history entry and inspect the local output rather than relying only on an uploaded preview.

5.1 Compare the captured file with the delivered file

Open the original local image at 100 percent. Then compare it with the image in the editor, clipboard, upload destination, or messaging application. Some websites and chat services create scaled previews that can look cropped even when the source file is complete.

If the local file contains every section, the scrolling capture succeeded. Stop changing capture settings and troubleshoot the later destination or workflow step instead. Confirm that you uploaded the correct file and that the destination supports the image's dimensions and file size.

5.2 Look for processing or save errors

Review visible error messages and ShareX logs if the image was not saved, an editor action failed, or the task ended unexpectedly. Logs are more useful when there is an explicit failure than when the output is merely stitched incorrectly.

Note the time of the capture, selected region, browser, page type, monitor, zoom level, and whether the cutoff was repeatable. If you report the problem, include a sanitized example page or reproducible test when possible. Avoid sharing screenshots or logs containing private URLs, tokens, account information, or confidential page content.

6. Quick Fix Checklist

• Test a short, static page to confirm that basic scrolling capture works.
• Select only the scrolling document area, not the entire browser interface.
• Dismiss cookie banners, chat boxes, popups, and floating controls.
• Exclude sticky headers and independently scrolling sidebars where possible.
• Set browser zoom to 100 percent for the diagnostic test.
• Keep the browser on one monitor with consistent Windows scaling.
• Slow scrolling or increase capture delay so each frame can settle.
• Preload lazy images by scrolling through the page before capturing.
• Capture infinite feeds in defined, shorter sections.
• Check the original local image before blaming an upload destination.
• Review crop boundaries if the same middle section always disappears.
• Manually crop repeated headers when all underlying content is present.

Change one condition at a time and repeat the same test. Once the output contains every required section in the correct order, stop adjusting settings. Additional changes can reintroduce the problem or make it difficult to identify which fix worked.

7. Frequently Asked Questions

7.1 Why does ShareX cut off the bottom of a long page?

The page may still be loading, the scrolling action may stop before reaching the true bottom, or infinite scroll may add new content after capture begins. Preload the page, wait for its height to stabilize, and test a shorter range. Also make sure a popup or internal panel is not intercepting scrolling.

7.2 Why is the middle of my scrolling screenshot missing?

A missing middle section usually indicates a failed frame match. Large blank areas, repeated layouts, sticky elements, animation, or insufficient stable overlap can cause it. Narrow the capture region, slow the capture, and start from a slightly different position so the overlap contains distinctive content.

7.3 Why does the same header appear multiple times?

The header is probably fixed to the viewport while the page moves underneath it. Exclude it from the selected region, collapse it if the site allows that, or crop the duplicates manually. Manual cropping is the sensible endpoint when the body content is complete and correctly ordered.

7.4 Can browser zoom cause incomplete ShareX captures?

Browser zoom can change responsive layout, dimensions, and pixel alignment. Testing at 100 percent removes one variable. If that fixes the issue, use 100 percent for the capture or test another stable zoom level without changing Windows scaling simultaneously.

7.5 Should I reinstall ShareX when scrolling capture is incomplete?

Not as a first step. A partial but stitched result usually points to page movement, region selection, timing, scaling, or workflow processing rather than a damaged installation. Reinstallation is unlikely to fix a sticky header or lazy-loading page. First verify the issue on a short static page with a capture-only workflow.

7.6 What should I do if no setting produces one complete image?

Divide the page into shorter overlapping captures. This is often the most reliable approach for infinite feeds, web applications, independently scrolling panels, and extremely long pages. If the failure also occurs on simple static pages, document the repeatable setup, review logs for explicit errors, and consult ShareX support resources with a nonprivate example.
