Flickering artifacts 3440*1440@240Hz MSI Geforce 4080

Continuing the discussion from DisplayPort DSC 4K@240Hz flickering artifacts:

Hi - On Linux Mint 22 Cinnamon, Kernel: 6.8.0-48-generic
Geforce 4080 (MSI Gaming x trio) Drivers 550.127.05
Display is LG ultragear with g-sync enabled.
Screen started to flicker right after mainboard bios update (MSI PRO Z690-A wifi). It is the exact same flickering as in the discussion above. Everything was fine before the bios update.

I made several tests and the only way to get rid of this is to run on wayland ( but wayland is not yet mature and comes with drawbacks)
I tested Ubuntu 24.04 (fresh install) with gnome and the same flickering happened except with wayland.

Any help would be appreciated,
Thanks

I solved the issue this morning after 2 days i tought i would go crazy!
I just turned off the nvidia settings-> OpenGL settings->“allow flipping” on drivers 560.35.03.
As easy as this :-)
Hope it will help others

Thanks for your finding! I confirm that the issue persists and that disabling the Allow Filpping option eliminates it.
