I am facing a strange problem every 2 minutes or so. Half of the screen goes black and comes back very fast. I have an 144Hz monitor and an Nvidia GTX 1650 Super. The problem appeared when I upgraded the Nvidia driver from 525 (to the current one). I attach the nvidia-bug-report.log.gz
I am having the same issue on my Asus G14 laptop running a GTX 1650 Ti connected to an external monitor supporting 3440x1440 @ 100Hz via usb-c to DP. The issue seems to occur only when going above 60Hz. I can’t replicate the issue on my windows installation using exactly the same configuration (dual boot) so it’s not a hardware issue.
My OS is Linux Mint 21.1 MATE. It seems to occur randomly every few minutes. I have tried different settings at Nvidia control panel without any improvement. My current drivers are 530.41.03-0ubuntu0.22.04.2.
Unfortunately MATE is based on gnome 2 and thus not compatible with Gnome 3. From what I read Mate had forked part of the code but it would be a challenge to install this gnome extension. Thank you for the suggestion though!
