I have had many GPU problems in my current install of Kubuntu (I keep things as updated as possible). The previous GPU, an RX 580 8gb, had overheating issues (now found to be a hardware problem) and a system crashing issue, and now my RX 5500 xt 8gb also has a problem of randomly crashing in the game Cyberpunk 2077, and so far nowhere else. The game seems to be unstable on its own, as it can crash and glitch outside of graphics crashes. I am running it in medium graphics in windowed mode, on proton hotfix.
I have followed the guide "Dummy's guide to AMD GPU Issues", and besides enabling "amdgpu.gpu_recovery=1" in grub (which hasn't stopped crashing), this is the output I have been able to gather of all the goings-on in my system:
