Here are related issues and discussions for issue #11208 ("Console logs on webfrontend resource scrolls too much"):
Highly Relevant Issues and PRs
Issue #7969 (March 2025) - Console logs not showing, plus browser window size affecting displayed logs
- Summary: Reports multiple console log UI problems, including missing logs, logs not refreshing, and incorrect/exaggerated scroll size/space. The issue is sensitive to browser window height and appears/disappears unpredictably. There is mention of excessive empty space after the last log entry, which may relate to "scrolls too much."
- Discussion: Several users confirm the issue, and it is noted that Aspire 9.4 added an option to not wrap log lines, which can help. However, even with wrapping off, some users still see disappearing logs and excessive scroll space. The problem is present across widgets that use virtual scrolling.
- Recent Comments: Video evidence requested; ongoing investigation.
PR #10740 (July 2025) - Fix automatic scrolling to the bottom of main page content
- Summary: Addresses broken scrolling behavior in structured logs and traces, including scroll bar jumping and automatic scrolling. Improves overscan and fixes flag handling for scrolling.
- Discussion: Video feedback suggests some issues remain, but author believes structured logs are correctly scrolled to the bottom.
PR #10861 (August 2025) - [release/9.4] Fix grid scrolling bugs
- Summary: Backport of #10740. Fixes grid scrolling races and erratic mouse wheel behavior in large grids, which could cause excessive or broken scrolling. Increases overscan for virtualized grids to improve user experience.
- Discussion: Approved as a low-risk regression fix for 9.4.1.
PR #10883 (August 2025) - Switch grid display mode to fix scrolling
- Summary: Refactors grid display to table mode, updates column sizing, and reduces overscan to improve performance. Notes some remaining issues with FluentUI, but aims to address scrolling problems.
Issue #6978 (December 2024) - Logs UI Glitching
- Summary: Reports logs UI glitching when scrolling, with text vanishing and reappearing. Occurs in Firefox and Chrome. While not exactly "scrolls too much," it is related to erratic scroll behavior.
- Discussion: Some users report the issue resolves itself after tweaks; others confirm ongoing problems.
PR #3776 (April 2024) - Make console log page usable on low-res/high-zoom
- Summary: Attempts to improve console log page usability for low-res/high-zoom users. Reviewer notes that the change breaks scrolling, causing the header to scroll with the content (not desired).
- Discussion: Suggests further testing and CSS tweaks to avoid breaking regular usage.
PR #4245 (May 2024) - Improve summary details view / toolbars / navbar experience on desktop for low-vision users, as well as mobile users
- Summary: Refactors page layout for accessibility, including scrollable content at low page heights. Multiple comments discuss scroll bar visibility, excessive padding/margin, and unnecessary scrollbars—issues that could cause "scrolls too much."
- Discussion: Some scroll issues are acknowledged as Blazor limitations. Fixes for console logs updating after layout are mentioned. Line number bugs are discussed, but not directly related to scrolling.
Other Related Issues
Issue #2553 (March 2024) - Structured logs and traces pages scroll position when returning
- Summary: Structured logs and traces pages sometimes reset scroll position to the top when navigating back, rather than staying at the bottom. Fixed by PR #2831.
Issue #6281 (October 2024) - Bad experience when viewing console logs for a resource with a lot of logs
- Summary: UI freezes and behaves badly when loading large amounts of logs, due to streaming from oldest to newest. Discussion includes suggestions for limiting log history and improving loading direction. Not directly about excessive scrolling, but related to log rendering performance.
PR #10271 (July 2025) - Add option to console logs to wrap log lines
- Summary: Adds an option to disable line wrapping, which can help with scrolling issues when log lines have unequal heights.
Conclusions
- Regression from 9.4: Multiple issues and PRs confirm that scrolling behavior in console logs and related pages has been a source of regressions, especially around Aspire 9.4 and later. Several fixes have been merged, but some users still report problems with excessive or erratic scrolling.
- Virtualization and Overscan: The root cause often relates to the use of virtualized grids and overscan settings. Increasing overscan improves scrolling but may not fully resolve all edge cases.
- Browser/Viewport Sensitivity: Problems are sometimes sensitive to browser window size, zoom level, and switching between desktop/mobile views.
- Ongoing Investigation: The team is aware of these issues and continues to refine scrolling logic, with several fixes already shipped and more planned.
