Wrong GPU driver and graphic artefacts

So, I’m new to linux in general and met quite an unpleasant bug of graphic artefacts when I interact with windows or taskbar (like old rainbow tv stuff all over what I interact with, it’s not like every time but every 5-10 it appears). I tried to search my problem and at one point thought about GPUs.

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA107 [GeForce RTX 2050] [10de:25ad] (rev a1)
	Subsystem: ASUSTeK Computer Inc. Device [1043:1dc3]
	Kernel driver in use: nvidia
--
05:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Rembrandt [Radeon 680M] [1002:1681] (rev 0b)
	Subsystem: ASUSTeK Computer Inc. Device [1043:1dc3]
	Kernel driver in use: amdgpu

This bug only appears when I use my AMD (in-built) GPU because when I play game and use my nvidia this bug never appears.

glxinfo | grep -e OpenGL.vendor -e OpenGL.renderer
OpenGL vendor string: AMD
OpenGL renderer string: AMD Radeon 660M (radeonsi, rembrandt, LLVM 19.1.5, DRM 3.59, 6.12.10-202.bazzite.fc41.x86_64)

And here is a thing… My laptop uses 660M radeon driver while I have 680M radeon. I don’t know whether it is the issue which creates all of this (as well as sometimes something bugs and I cannot use my pc because there is 0 fps and moving my mouse moves it to the other edge of the screen. Reboot fixes it). So… I wanted to ask for help how to change the driver and whether it’s actually an issue, after all of those specific drivers for each GPU must exist for a reason.

I’ll be very grateful for anybody willing to help.

The driver is correct as the amdgpu is for the amd gpu.

All amd drivers are in the kernel so there is no need to “change” anything.

Okay, I see, that’s good if the drivers are ok. But still maybe do you have a clue what possibly may inflict graphic bug while using amdgpu/desktop while not gaming? The bug is unrecordable (tried to record it using obs) and it never was an issue when I was on windows. So I’m truly clueless what causes it.
Still thank you for the driver clarification.

For the record, I am also experiencing gfx artifacts on one of my machines with built-in amdgpu, and that’s not even on ublue, but plain Fedora 41. It appeared few weeks / months ago. Didn’t have time to investigate yet.

I found solution for me (completely randomly) setting adaptive sync on always in display configuration and no more graphic bugs. You may try it as well, maybe it will help you too, won’t hurt anyway.

Hey,

you can also try the following, and see if solves it permanently:

sudo rpm-ostree kargs --append=amdgpu.dcdebugmask=0x10

then reboot.

I tried to set this in grub but it didn’t fix it for me. Adaptive sync “always” did (for whatever reason). Still thank you for trying to help, I’ll save it if graphic artefacts appear again.
