#StackBounty: #ubuntu #gpu #amd Ubuntu 20.04 screen flicking and glithing

Bounty: 100

I’ve installed ubuntu 20.04 in my computer, and I’m having troubles with some flitchig and flicking.
My specs are those:
Amd Ryzen 3 3200G With Vega 8 GPU
16GB of RAM DDR4 3200MHz
Mother Board Gigabyte B450 DS3H
SSD Samsung EVO860
I’ve been trying some config in grunt but didn’t worked, this are the solutions I’ve been trying up:



The last thing I’ve done is log in in "ubuntu on wayland" and the flicks and glitchs reduced a lot, but it still happening sometimes

This is what was happeing

After "ubuntu on wayland" it’s working better, but still glitching sometimes:

I though that maybe the problem was the OS, so I’ve tried to install Debian, but when I was chosing graphical installation, this was happening (tried 3 times, and allways the same)


So I think that maybe the vega 8 isn’t at all compatible with ubuntu, but This computer MUST be used on linux.


Maybe if I try another desktop environment that is not GNOME it could work better?

Get this bounty!!!
