It doesn’t matter much what Linux you use. Rather what is your desktop environment? (KDE Plasma, Gnome, sway etc.)
On KDE for example there is a shortcut to restart the compositor, which might fix your issue.
But in general you might have luck “restarting” it by switching the tty. You do that by pressing CTRL + ALT + some function key between F1 and F8 (the standard gui tty number depends on the distro). Try to switch to a non gui tty and then back.

For example, on my distro I would do:
but on yours it might be F7 or some other.
I agree with Ctrl+Alt+F1/F2 but would add
init 3 init 5
but I learned for my case its better to reboot if my GPU is acting up the instability would eventually come back
the init command probably only works in Debian nowadays givin it’s a thing from the sysvinit era
