Linux <redacted> 6.12.7 #1-NixOS SMP PREEMPT_DYNAMIC Fri Dec 27 13:02:20 UTC 2024 x86_64 GNU/Linux

System is a Zephyrus G14 2024 with an NVIDIA GeForce RTX 4070 Max-Q / Mobile GPU. It's running on a 4K monitor (3840x2160) at 240Hz with 1.333333 scaling.

Description

When setting the vrr property to 2 and rebuilding config (NixOS), if I switch between workspaces quickly, there is an obvious pink flash artifacting seen. If I disable vrr by setting to 0, the issues goes away. See video clip for example.

WARNING FOR EPILEPTICS: Video clip contains quick flashing changes on screen.

How to reproduce

1. Set vrr property to 2
2. Reload the config
3. Quickly switch between workspaces with open clients.
4. Set vrr to 0 to eliminate issue.

Looks like one workspace has a fullscreen app and pink artifacts are caused by quick vrr on-off toggling.
Might be fixed with #9226 for regular fullscreen apps.

Thanks for your reply. I have two clients on WS1 and nautilus on WS2. Will check out your issue linked.

ensureVRR gets called every time workspace changes but doesn't return early when vrr is in correct state already. resetExplicitFences and other stuff might be the cause of this issue. resetExplicitFences shouldn't be called without waiting for existing fences.
