--- Comment #7 from Harry Wentland <harry.wentland at amd.com> ---
Does your kernel tree have the following patches?

90fef6476917 Revert "drm/amd/display: disable CRTCs with NULL FB on their
primary plane (V2)"
c7bd22893408 Revert "drm/amd/display: fix dereferencing possible ERR_PTR()"

If not can you grab the latest drm-next-4.18-wip and check again? Those reverts
should have fixed problems where mouse movement would slow the system down.
