Very recently I have run a dnf upgrade (on F42), updating my xorg-x11-drv-nvidia.x86_64 packages.
Immediately after rebooting, all of my menus were glitching, most primarily when moving my cursor. My Panel items, shadows and appbars are going invisible-visible insanely fast.
It’s most prevalent when running xpenguins, attached here: Watch Xfce glitches | Streamable (Sorry for the 3rd party link, I have no idea how else to attach this.)
Notice that I recorded this from phone and not OBS. For some reason, this glitching issue completely stops once I hit record with OBS (but not when it’s idle).
This also only occurs on Xfce. GNOME Xorg session works really fine.
Things I’ve tried:
- Switching to Intel iGPU: All worked perfectly
- Switching to Nouveau: Xfce freezes (I prefer proprietary anyways)
- Re-installing the Nvidia drivers from nvidia.com - both MIT/GPL and proprietary - The same result
Any help would be appreciated
