Where's the YouTube video? I see you mousing around a web browser window on the megarelease announcement, and I see a PiP window on the side, but I don't see a glitch in a YouTube video.

I don't see a glitch in your video. Can you point out what I should be looking at?

I see now, thanks. I think it is very likely this is a GPU driver issue, but I'll let the KWin folks confirm.
Yes, this is https://gitlab.freedesktop.org/xorg/xserver/-/issues/1317, and will be fixed in future versions of Xwayland and the NVidia driver.

Or fixed version
Yes, it's https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/967. That on its own will resolve most of the problems with some performance cost, and some future version of the NVidia driver (probably 555) + https://invent.kde.org/plasma/kwin/-/merge_requests/4693 will fix it completely (without a performance drop).
