SUMMARY A Thumbnail Aside overlay is only updated if the parent window is visible on the same Activity. STEPS TO REPRODUCE 1. Open a window (e.g. playing a video) on Activity A 2. Show a thumbnail aside for that window on Activity A 3. Switch to Activity B OBSERVED RESULT The thumbnail is no longer updated and shows a still image. EXPECTED RESULT The thumbnail should still be updated. SOFTWARE/OS VERSIONS Operating System: EndeavourOS KDE Plasma Version: 5.20.0 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 Kernel Version: 5.9.1-zen2-1-zen ADDITIONAL INFORMATION This seems to be a regression in 5.20?
Seems to work again.
(In reply to Schlaefer from comment #1) > Seems to work again. I'm having similar issue with this effect since 5.25. When I play youtube in fullscreen and enable this effect before minimizing the window, it used to play the streaming flawlessly up until 5.24 but now it looks like it only updates the video thumbnail when either mouse is hovered over a panel or virtual desktop is switching constantly. Is this a known bug? This kwin effect was one of my favorite since I like playing youtube in the background while working. I really miss this feature and hope KDE will bring it back soon. Thanks
Situation with 5.25 here: Minimizing the source window or having it on a different activity/virtual desktop stops updating the thumbnail.
