Just did a clean single boot install of Bazzite for nvidia, gaming mode build. 5800X3D, 3070 FE, 32GB 3600 RAM.
Steam works fine in the desktop mode, but get terrible artifacting/flickering in the BIg Picture mode... the only time the screen stays stable is when I move the mouse. I have also enabled all of the GPU accleration ticks in the Steam Desktop mode, still getting the Big Picture wierdness.
Is this just still a growing pains with Nvidia thing?
