Hi,

It seems that you are running without PRIME Sync. Running PRIME without sync capability is expected to result in OpenGL applications failing to sync to vblank.

Looking at the bug report, it seems that all of the system requirements for PRIME Sync are present, so the only additional requirement should be loading the nvidia-drm kernel module with parameter modeset=1. This can be tested by running “sudo rmmod nvidia-drm; sudo modprobe nvidia-drm modeset=1” without X running. If it works, it can be made persistent by adding “nvidia-drm.modeset=1” to the kernel command line.

Thanks,

Ryan Park
