Dolphin after playing the video

confirmed in Dolphin 21.12.2 with KDE 5.24.5 with Frameworks 5.93
Comment 3 Firlaev-Hans 2022-05-28 20:00:13 UTC 
Can confirm on Arch and Dolphin 22.04 when using Wayland at least (haven't used X11 in a while but I'm pretty sure it was fine there).

>(even for video file only the audio will play)
In some cases the video will actually at least show some frames (but won't play properly).

And in general, besides becoming "unresponsive and slow", the whole UI suddenly gets graphical glitches all over the place, with parts of the screen not updating properly. Only after restarting Dolphin it goes back to normal.

Possibly you are facing bug 445196
Comment 5 Firlaev-Hans 2023-11-12 11:52:15 UTC 
Works as expected without glitches in KF6/Qt6 builds of Dolphin
