I’m Trying to use my Freesync feature on the 144hz monitor, while i play games or using the vrrtest utility the screen flickers black while in VRR range of 48-144hz. the blackouts are just 1-3 sec but can be really consistent or non for a few minutes. i tried downgrading to 470.82.00 which made the problem worse. 495.29.05 seems to produce a lot less flickers but are still existing. i tried setting custom hz to 120 but no change.
On Window with the latest available game ready driver i had no issues. neither between 48-144hz nor under it.

I have this issue as well if the screen goes to sleep. I can fix it by changing the refresh rate to 120 and then back to 144hz.
This appears to be the same bug as this: NVIDIA 470.74 Breaks Gsync (Compatible) Support (Monitor Modulates between 0 or 144hz and Flickers black)
If anyone running Ubuntu has this issue, can you please click on the “Affects me” link on this bug I’ve raised: Launchpad Bug for Ubuntu
I’ve fixed my issues in Ubuntu 21.10, for any linux users experiencing a signal loss momentarily 1~2 seconds during changing of GPU accelerated program with NVDIIA with G-SYNC and Flipping enabled, in my case the issue was related to my user profile. I created a new user to test and could not reproduce the issue.
I had tried the following drivers, but the issue persisted:
470.86, 495.44, 495.46, 510.39.01.
I had also tried resetting my NVIDIA settings in my profile by removeing ~/.nv and .cache/nvidia.
My guess is that something happened during distribution upgrade with dconf or in my .config folder that caused this issue. To resolve this problem I performed the following steps:
- Ensured I had set a root account password
- Backed up critical bits of software/configuration
- Logout to login screen
- Change to terminal [Ctrl+Alt+F5]
- Login as root
- mv /home/username /home/username.old
- cp -rT /etc/skel /home/username
- chmod username:username /home/username
- [Ctrl+Alt+F1] to return to GDM login screen
- Login as user
- Restore files, settings and configuration from /home/username.old & /home/username.old/.config as required
