STEPS TO REPRODUCE 1. Open Firefox with many separate windows. 2. Hover mouse over task manager to preview windows. OBSERVED RESULT It show duplicated previews. EXPECTED RESULT It should show previews for each separate windows of Firefox. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210217 KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.10.16-1-default OS Type: 64-bit Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-3770 CPU @ 3.40GHz Memory: 7.5 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4000 ADDITIONAL INFORMATION Same issue report on reddit: https://www.reddit.com/r/kde/comments/lou60a/why_is_plasma_521_showing_the_same_preview_on/
Current workaround: disable enhanced media controls in plasma integration addon settings. But I think Task Manager shouldn't bother showing media thumbnails at all, live preview of the actual window content is in ~all cases more useful.
