--- Comment #56 from Nicholas Kazlauskas <nicholas.kazlauskas at amd.com> ---
It seems to be the frequent calls to DRM_IOCTL_MODE_SETPROPERTY that's causing
the issue but I'm not entirely sure what specifically it's trying to set that's
doing this.

This probably isn't triggering anything that really needs hardware programming
but it will end up waiting for all outstanding atomic commits to finish which
would likely explain the stuttering.

Does this patch improve the issue?
