<pre>I think I have it resolved:
commit 3855a728e5522452f0d6208e569ef23389d32d20

sna: Always restore the scanout on DPMS on
As we may exchange the frontbuffer whilst the outputs are hidden (DPMS
off), when we turn them back on, unless we force the CRTCs to be
updated, we may end up simply showing a stale scanout buffer not the
current frontbuffer. If the two are same, it will just be a kernel
no-op.
