Yes, I've been bothered by VRR flicker on my OLED monitor (LG 27GR95QE) since I started actively gaming on it with my Linux build a couple months ago, it was never an issue with consoles for me.
I'm on KDE FWIW, and the flicker is more pronounced during games with mouse cursor on screen afaict. I can't compare to Windows.
I think VRR flicker is less of an issue when running games within a gamescope session, but it's not ideal either.
If the issue is more prominent when the cursor is showing, it could be the hardware cursor (default on KDE) causing the issue. When you use hardware cursors, the cursor is rendered on a different 'plane' on top of the rest, possibly causing desync. You could try disabling it with a environment variable (I think it was
KWIN_FORCE_SW_CURSOR=1
), forcing to software render the cursor.Oh, TIL - I'll have to try that, thank you!
Kind of a bummer to hear - I was hoping KDE's VRR implementation might avoid the issue. It may be a Wayland problem so that would be unavoidable.
Edit: did some testing with a live image tonight - at least on my machine KDE seems much better when it comes to flicker
