<pre>I can confirm that this patch does indeed fix it:
f9cd7b881a042dcc8f1b1236ecea6deb3eb4d5bd drm/i915: Move sprite/cursor plane
disable to intel_sanitize_crtc()
To get it to apply cleanly against 4.3-rc5, I
reverted
721a09f7393de6c28a07516dccd654c6e995944a drm/i915: Add primary plane to mask if
it's visible
Then applied:
7f4c62840cc416986f983a8c68f7010c97e06daf drm/i915: Assign hwmode after encoder
state readout
f9cd7b881a042dcc8f1b1236ecea6deb3eb4d5bd drm/i915: Move sprite/cursor plane
disable to
intel_sanitize_crtc()
b26d3ea323b41a56db74f46131bc89e3c485f365 drm/i915: Add primary plane to mask if
it's visible (4.4 version)
Can we get a backport to 4.3?</pre>
