hose
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 adjustmen=
ts
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
