I am having a problem with my Linux desktop and hoping this community can help. The hardware is only about a year old: CPU: AMD Ryzen 7 7800X3D, GPU: AMD Radeon RX 7900XTX. I am running KDE Plasma 6.4.4 on Wayland. My distro is Feodra 42, and I keep up with regular updates. Kernel version is 6.15.9.
Lately, I have been getting a flicker of horizontal white stripes occasionally coming across my monitors. It does not seem to matter what the program on the screen is. They’re not making it impossible to use the computer, but it is very distracting when it happens. I am also worried that it may be the hardware failing, but I am hoping it’s just a driver issue.
Is this a known issue with AMD drivers? Part of my concern is that last year I installed amdgpu and rcom from the AMDGPU and ROCm repos to play with AI models locally. Now I am wondering if that is messing with my video drivers. How can I tell which ones are being used? If I want to go back to the stock drivers, do I just uninstall the amdgpu package with dnf?
I’ve had similarly described visual issues in the recent past on an amd rx 7600xt under Bazzite (based on Fedora 42). It turned out to be the cable was failing. Swapped cables and it hasn’t happened since.
