Created attachment 145139 [details] [review] 0001-drm-amd-display-Test-patch-for-disabling-color-adjus.patch >From your video it looks like something is issuing a lot of full updates. Those are slow enough that they can miss the current vblank window and be forced to wait until the next one with vsync on. I've attached a debug patch you can try that should disable color adjustments from triggering full updates. I've also added some debug information to know when full updates are being issued in case it was something other than color management. You can view that output with log level 4, ie. echo 0x4 > /sys/module/drm/parameters/debug
