Diagonal tearing on X11

Do you really believe your eyesight can go above that?
Anyway …
But in the end, did you or not rebuild the AUR package as i hinted on your other topic?

From the LookingGlass documentation, it seems it passes trough whatever GPU there is, without the need of a separated dedicated GPU, so, why are you keeping the RTX 3060 via vfio-pci ?
