Any chance you could run inxi -Fzx and stick it into a pastebin? I’ve just tried to replicate this on 5.21 /w nVidia and I can’t get the same issue. Knowing your spec and settings would help, but first step could possibly be checking if you’re getting any compositing errors.
Great stuff, thanks. Can you confirm if you get the same issue
a) When nothing else is actively running in the background
b) If you have compositing turned off, i.e. switch to xrender
There’s nothing blatantly obviously bottlenecking, but others may be able to offer additional guidance. I’d start with graphics config/drivers and work down. For what it’s worth, I’m running an RTX3070 with nvidia drivers and not having the same issue on compositing under OpenGL 2.0
Interesting! I don’t use wobbly windows, but I temporarily enabled it and can replicate what you’re seeing. This isn’t something I could pick up on all my windows are either maximised or minimised. Sure these teething problems will be fixed in the upcoming point releases if the devs know about them.
If you get a chance and you’re comfortable doing so, it would be a huge help if you could log your issues via https://bugs.kde.org/ - I can’t see a similar bug logged currently, but my keyword search has been minimal. Thanks!
