There is a problem while playing VULKAN (or dxvk) games with nvidia optimus render offload on xwayland.
When playing a game, if framerate does not keep up with vsync rate (60fps in my case), screen starts glitching by momentarily showing some frames that were rendered a little earlier.
OS: Manjaro [testing branch]
Kernel: Linux 5.10.54-xanmod1-1-lts
Hardware: HP dc0019ur (Omen 15) Laptop with Intel UHD630 + Nvidia GTX1050 2GB
Relevant bleeding-edge packages installed (from AUR): xorg-xwayland-git, libdrm-git lib32-libdrm-git, xf86-video-intel-git. Installed these thinking it may resolve the issue. but it didn’t.
