So the desktop would need use V-Sync when no full screen app is running, so that the screen is refreshing at it maximum rate?

Same behaviour while gaming ? intense flickering ?

@Trillon008 I didn't experience this issue while gaming only on the desktop. It seems as though it was fixed with this update today. The desktop is at the static 144Hz and when I launch a game VRR works like it should. I'm hoping this is kept going forward. I can finally work without having to swap VRR on and off.

xorg-server is upgraded from 1.20.8-64-1-x86_64 to 1.20.9-65-1-x86_64 with delta.

It still doesn't work with nvidia (gtx 1660 super). Games work flawlessly but the desktop still flickers (I'm on budgie) due to VRR being enabled. I have also the latest updates according to last Friday's sync. Is there anything that can be done to fix this behavior? Thanks.

@Framani I'm using the unstable repository with Plasma. VRR is still disabled on the desktop like it should be hopefully these changes get synced to stable soon.

I'm also in the unstable repository and both plasma and budgie still suffer from the flickering on desktop. It hasn't been fixed yet. You might have "pipeline composition" and "enable g-sync" in the nvidia settings, but having both enabled disables VRR. Once again, this is what I have observed and I hope a fix comes sooner or later.

@Framani I don't have pipeline composition enabled. I'm using driver version 450.66. I attached a video showing me tabbing between the desktop and Overwatch. We can see VRR disables on the desktop and enables when the game is in full screen.

@WannaBeOCer I honestly don't know what's wrong with my PC. I'll keep trying out to see if I can solve my issues. Do you have any other setting enabled in the nvidia control settings? I might've overlooked something.

@Framani I didn't change any other settings. It just started working one day after installing updates. I would keep this request open until someone confirms they resolved it.

@WannaBeOCer It works marvelously in games, but the refresh rate flickers like crazy on the budgie desktop. The strange thing is that I have two options for 144hz "144hz (1) and 144Hz (2)". Don't know why tbh. With both option I get the same results.

This is still a issue in 2021. Latest everything and using KDE... Makes it unusable unfortunately

@DataDrake I noticed this behavior continues again but instead of flickering I'm getting a black screen that flashes when opening apps. If I disable GSync Compatible I no longer get the flashes. I'm currently using a Titan RTX, LG 27GN950 monitor and DP that came with the monitor. As stated previously the issue doesn't occur on KDE Neon, Fedora 32 and openSUSE Tumbleweed. The main difference I observed is that they lock the refresh rate on the desktop while on Solus, Adaptive Sync is enabled on the desktop.

When I was using my Radeon VII on Solus I had the flickering issue which was in the OP with my old Acer XF270HUA monitor.

@WannaBeOCer This sounds like maybe an issue with kwin then. Are you still experiencing this?

@DataDrake I switched back to Budgie a few months back by performing a fresh install and the black screen flashing issue occurs there as well but not as frequently. I noticed the flashing only occurs on Budgie when using Steam or Lutris or launching full screen games. If I perform a screen recording the black screen flash isn’t present. I did try multiple different DP cables with the same result. Let me know what logs I should check. If needed I’ll upload a video later this week.

When using KDE the flashing would trigger when opening the Application Launcher along with steam and other full screen apps.
