Graphics Issue with Budgie 18.04, AMD and Intel Integrated

Budgie Desktop

I’ve been experiencing some weird random graphical glitching after doing a fresh 18.04 install. Anyone have a clue? I’m running an AMD Radeon RX550 and onboard Intel graphics using open-source drivers.

I’ve seen the graphical glitches like this. I too have the same card as you but in my case it only last for 10 seconds.

I tried the AMDGPU-Pro driver, but the issue I have is that if I do that, I can’t seem to make the onboard Intel graphics chip work with it. I’m not entirely sure, but it might not be supported. Correct me if I’m wrong.

I did not have this issue under Budgie 16.04 LTS.

My understanding is that the AMDGPU-Pro driver is being deprecated - much more focus on the open amdgpu stack by AMD themselves. Suggest stick with that.

That’s what I’m planning to do anyways. I do think it might have something to do with Mesa. I’ve tried the git-release of Mesa (18.2.0-devel) and the graphical glitching seems to be worse, causing entire sections of the screen to just go white in addition to the glitching shown in the screenshot. Like I said earlier, AMDGPU-Pro doesn’t exhibit any of the issues, but of course I don’t want to use it since I lose a monitor (and it being deprecated, of course). I’d like to keep this FOSS.

To help along, here’s what I have (before updating to 18.2.0-devel version of Mesa).
