<pre>It seems that when wayland starts the CRTC is active but the primary plane
doesn't have an FB. A call to drmModeCursor() is done before any mode set, and
that causes the watermarks to be updated, but the update considers the CRTC is
inactive because of the lack of a primary fb. The drmModeSetCrtc() call that
follows is short circuited to a flip, so that also doesn't update the
watermarks, causing the system to run with watermarks set for a disabled CRTC.</pre>
