The settings should be retained.

I solved my issue by navigating through the garbled GUI, like a point and click pro.
I hit the super key, typed in tweak, hit enter, then carefully made it down to "windows" tab, then selected Marco(No Compositor). It is possible to do it even with the stair step effect if you carefully estimate the location of the pointer.
Problem solved instantly.

the terminal command didn't work for me
Had this before, just wanted to report that the work arround didn't work for me
Unfortunately, none of the regular QA or Dev Team members has an AMD GPU to test this.
Thus we are forced to rely on user reports and reports from other flavors to help troubleshoot.
We appreciate all the reports and troubleshooting steps everyone is providing.
I'm having the same issue, my computer, a laptop Lenovo is unusable due to this problem.
Is there any way to fix it? : (
After a few tries (moving around the settings) this worked for me. Thanks!
Has this not been fixed? Looks like its back to regular ubuntu for me.
No, I have had the same problem installing Ubuntu Mate today.
The bug is still around.
The solution has been to select Marco (No Compositor) as starseed-pl suggested on his post from 8 may.
Isn't it a pity? A brand new system and no compostion available...

I think I remember it subsiding after many updates and reboots, and eventually I recall being able to switch to GPU compositor. Unfortunately IDK what I did. I installed many packages and did a lot with that system configuration because I was streaming my proton games with it. I can no longer replicate the bug though because I stuck that card on a mining rig I built, which is running 18.04.4 version of MATE.
Hi, I just installed compton and compton-conf and I got a compositor running on my desktop. When the bug gets solved I'll go back to Marco. Until then it's a solution.
I am having issues with monitor going like a snow storm, its not a freeze.
AMD Ryzen 5 2600 Six-Core Processor × 12
Radeon RX 570 Series (POLARIS10, DRM 3.37.0, 5.4.0-40-generic, LLVM 10.0.0)
I watched a guy on youtube, very helpful
Still does snow storm, it happens once every 24 hours or more.
Any ideas please.
I love Ubuntu Mate 20.04, please dont tell me to install 19 or 18
Hi

It can be a parasite on your wiring.
