Cinnamon 4.6 makes my display flickering

[Marco Guazzone]

Hi,

I have just upgraded Cinnamon to the new 4.6 version with dnf and then
rebooted the system.

When I log in, Cinnamon makes my screen flickering, with half screen blue
and the other half screen showing (a half of) my background image.

Just for testing, I created a new user to start Cinnamon with a fresh new
configuration. Same problems experienced

If I use Gnome shell (Classic), then I log out, and then I use Cinnamon the
problem disappears, apparently.

Any idea?

Thanks for your help.
Marco
