Radeon 7900 XT screen glitchy

I recently built a new PC, with the Radeon 7900 XT as the GPU, and got the classic invisible-mouse-cursor during install, but persevered, only to find that my graphics randomly starting glitching out in “blocks” on both my monitors. I assumed this was a X11 thing, and swapped to Wayland, to the same issue.

Please see the link for how to properly format your output.

You have BIOS updates available. You should definitely do that with newer hardware.

A similar thing may be said of kernels. Keep the 6.1 LTS but try out newer ones - 6.3, 6.4, probably aiming for 6.5 whenever it is available due to some known kernel bugs.

This should probably be using the modesetting driver.

sudo mhwd -i pci video-modesetting

This makes it appear like maybe the amd is taking precdence?

You have a dual-gpu setup. You may have options to disable the intel gpu in BIOS.
But we should look at the current situation:

glxinfo | grep 'renderer string'
DRI_PRIME=1 glxinfo | grep 'renderer string'

You probably want a swap of some sort - swapfiles are easy to add, for example:
I forgot to set up the swap encryption and I’m trying to set it up now - #2 by cscs
