Seems to be an issue with GPU driver. Can you check if this happens with official Nvidia driver? I am not sure whether we do support unofficial drivers. Also please provide model of your GPU.

hi, I'm using blender 3.4.0 on Fedora 37 on an XPS 15 9650 with Nvidia Optimus/Intel grahics. The issue shows up when using the Nouveau drivers, and disappears if I start blender with the intel graphics card.
UPDATE: installing nvidia drivers fixes the issue.

I did not get confirmaton from OP, so will go with info from @Andrea Ghensi (sanzoghenzo) and close this report, since this is driver issue.
