By the way, I'm on:
Endeavour OS
KDE

Hey, we might have the same issue. It looks like the menu is divided into small pixel-like squares, and then rendered by row first, before moving to the next column. Like instead if we read left to right then go to the next line down, it's as if we'd read top to bottom, and then go left before going top down again.

I'm also running EOS & KDE with (currently) nvidia-open-dkms 570.144-3. Are you also nVidia?

It started happening to me about the same time you posted this.

I have no solution yet.

I'm also on nvidia-open-dkms, the issue was present on nvidia-dkms as well as the non dkms version too though
It was like that for me since I installed my linux

But, I don't seem to have that issue anymore on X11 now
So it might be a bug currently on Wayland compositor

I'm back on Wayland, with Gnome now
And I had the issue again

It's resolved after going to steams settings, under interface and turning off
"Enable GPU accelerated rendering in web views (requires restart)"

This is also an issue on nixOS hyprland (wayland) with an nvidia gpu. It's scrambled with every right click menu, works correctly maybe 5% of the time.

Turning off the interface setting "Enable GPU accelerated rendering in web views (requires restart)" also fixed the problem for me.
