It is a kind-off related problem, as it was part of the fallout from the 1.18.2 fixes. commit 74b755fe0a786d330d121c435d274e2418003581 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Apr 6 22:50:28 2016 +0100 sna/present: Clear flags on the vblank event's CRTC early We store a flag on the vblank's CRTC to indicate whether we have marked the target CRTC as having an immediately pending vblank. We should clear this set of flags early so that we don't have to worry about the flag whilst processing the vblank, and so that we don't get confused if we have to requeue the vblank.
