Hi Maarten,

I cherry-picked your patch (with small change, as patch gave compilation error
on pipe definition; intel_crtc->pipe instead of pipe) on drm-tip
4.18.0-01978-g273ade7fd922

                        intel_crtc_disable_pipe_crc(intel_crtc);

+                       /* Wait a vblank for planes to actually be turned off
*/
+                       intel_wait_for_vblank(dev_priv, intel_crtc->pipe);
+
                       
dev_priv->display.crtc_disable(to_intel_crtc_state(old_crtc_state), state);
                        intel_crtc->active = false;
                        intel_fbc_disable(intel_crtc);

Issue is still reproducible. Attaching the logs..
