My last nvidia card (a 1050) had some weird non-obvious (likely hardware) issue that caused it to utterly lose its mind when faced with certain OpenGL shaders, but only when running the proprietary driver. It would throw bands of static on the screen or randomly drop the signal to the monitor. This persisted through several changes of kernel and driver version. It was solid under nouveau, but the performance suffered such that I noticed a lag even for just normal desktop use. In the end, I replaced it with an AMD card rather than attempt to troubleshoot it any further. My previous nvidia cards were solid, though.
