This bug was reported against an outdated version of KWin. We have made many

If the issue persists in newer versions can you reopen the bug report updating

Thank you for your feedback. If it's hard to reproduce, it's usually even
harder to fix :-( Not sure what can be done about this.

I have not noticed issues with video playback in a while.

Using my test application, I did get a rather stuttering 20fps -- but then
after restarting KWin, it is up to 60fps. So it seems like in principle KWin
can handle this properly, but sometimes it might get into a degraded state? Not
sure how to reproduce this though.

This issue report is quite old. Can you please confirm, that it still persists
with KDE 5.23?

As it's Intel hardware - same question as in every Intel specific bug report:
does switching to xorg modesettings driver improve the situation?
