SUMMARY
Icons-only Task Manager shows wrong thumbnails in firefox browser when a video
is played on one of its tabs
STEPS TO REPRODUCE
1. Open a video (such as https://www.youtube.com/watch?v=PtxtnIsqOEQ)
2. Play the video. Then pause it
3. Minimise the browser window. Hover over icon. It shows video thumbnail with
media controls, which is correct behaviour
4. Restore the window. Open a new tab (say www.google.com).
5. Hover over the icon with google in active tab. It still shows video
thumbnail with media controls. Minimise the window. On hovering over icon
again, the video thumbnail still persists
6. Now open a private window
7. Hover over the icon. Both previews show video thumbnail with media controls
and cannot be used to differentiate the 2 windows
OBSERVED RESULT
Video thumbnail persists in preview for every tab and window in the browser
EXPECTED RESULT
The window previews on hovering over icon should show the contents of the
active tab of the respective windows
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version:
KDE Frameworks Version:
Qt Version:
ADDITIONAL INFORMATION
Closing the tab with video immediately restores correct previews for all
windows.
"Keep windows thumbnail" was set to "always" in compositor settings
Plasma integration browser addon was enabled
