So, how i fixed the screen tearing on Nvidia proprietary driver:
Check if your V-sync is active:
sudo cat /sys/module/nvidia_drm/parameters/modeset
If the output is Y then it is active, if N do the following:
create a new file
sudo nano /etc/modprobe.d/nvidia-drm-nomodeset.confand insert the line:
options nvidia-drm modeset=1
Then:
sudo update-initramfs -u
Then check again with:
sudo cat /sys/module/nvidia_drm/parameters/modeset
Have a nice day to all!
