That doesn't sound normal, even for Linux. It almost sounds like the issue is somewhere else. My first guess would be a PSU that's unable to source the 3090's current draw under load, given everything else running on your system.

Try using a dedicated rail or another PSU if you have one.

Its definitely not. I have a V850 SFX Gold, a single 3090 FTW3 and a 7800X3D, and its rock solid in OCCT's variable load test, even when overclocked (and its not overclocked on linux).

I have literally all the exact same issues on my RTX 2060 Asus G14 laptop, like:

- GPU rendering broken in Wayland Chromium/Electron, and sometimes Firefox

- Occasional black screen on boot, from some kind of race condition.

- Unpredictable artifacting on the KDE desktop and some apps.

And I still get some of that when Nvidia DRM is disabled and I'm just using the 4900HS/7800X3D for display out. Completely disabling the Nvidia GPU fixes all of it, every single thing, but then I can't use CUDA.
