Nvidia RTX 3060 driver

I have a laptop equipped with a Nvidia RTX 3060 graphic card.
I installed Manjaro XCFE but the screen is unstable creating horizontal bands when moving the mouse.

I followed instruction to load proprietary drives and got the following message:

[vik19@vittorio-pd5x7xpnppnnpnt ~]$ sudo mhwd -a pci nonfree 0300

So it seems that proprietary drivers are already installed, but I still have problems.
Any suggestion?
Thank you!

Maybe it’s related to this?
Color banding and animation issues with 520.56.06 - Graphics / Linux / Linux - NVIDIA Developer Forums
Wait for the fix in the future release.

Thank you!
But you mean the future release of Manjaro or the future release of the Nvidia driver? I’m afraid the latter might be quite far in the future…

Wait for the new NVidia driver. They’re investigating the issue, so shouldn’t be too long.
