(Also: my video is 9.1M, which is bigger that maximal allowed attachment on
bugs.kde.org , so I had to upload the video to github instead. Please, raise
limit for attachment.)
Okay, so I'm able to reproduce the bug every time I want to reproduce it. So,
I'm in perfect position for debugging/bisecting, etc. So, dear KDE devs, if you
want me to bisect this bug, just tell me "please, bisect it", and I will do it.
But please note that I have free time until 22 Jan 2025, then I will move to
other things. So, if you want me to bisect, please tell me this until 22 Jan
2025.
The video was shot on fresh install of debian sid, with X11. "dpkg" reports the
following versions of packages:
ii kwin-x11 4:6.2.5-1 amd64 KDE window manager, X11 version
ii plasma-desktop 4:6.2.4-1 amd64 Tools and widgets for the desktop
The bug is also reproducible with Wayland on the same system.
The bug may be related to my GPU. Here it is (as reported by lspci):
00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-S UHD Graphics
(rev 04)
If you know how to disable GPU rendering/compositing in modern versions of KDE,
please, tell me this, I will try to disable it and try to reproduce the bug
again. (Long time ago I was able to disable GPU rendering/composition in
"kcmshell5 kwincompositing", but I don't see this option in modern versions of
KDE; that setting was handy for debugging problems.)
