Similar graphical glitches on a lot of games

hi, I’m having a problem when running some games. they have annoying glitches that I don’t know where they come from. i noticed it yet only on games running with wine/proton. I’ve noticed this bug on Remnant from the Ashes, Tell me why, Deep Rock galactic, and others.

specs:
AMD A10-9600P
8 GB DDR4-2400
Radeon R7-M340

unknown-36
unknown-40
examples above, i don’t have remnant installed now, but it happens similarly to deep rock, on the glow of team players
i can remember it happens on other games too, but can’t remember which.

What could cause this to happen and how can I fix it?
thanks!

based on ur specs, im assuming you have dual gpus, u sure that games are running on dGPU (i.e r7-m340)?

@SoxxZ
Have you tried amdgpu.dc=0 as a kernel parameter?

this seems to have fixed it! scrolled all arround this page and didn’t find this. thanks a lot!

the fix from @Dev0ut did fix it. but what is this parameter for?

Disable/Enable Display Core driver for debugging. Not sure it would be helpful?

the problem is already solved, so, i don’t need to
