--- Comment #30 from Chris Wilson <chris at chris-wilson.co.uk> ---
Ok, it prevents a glitch after a failure but introduces more strangeness. I can
live without that for the moment.
Respun the only use HW vblanks for the last frame and ran it through my
accuracy tests, no misses so pushed:

sna/present: Only use the HW vblank for the last frame
If that doesn't stop the starvation issue, I have no idea.
Looking through the logs, I haven't found a reason for the freeze. After the
failed unflip, it looks to be rendering back into the Screen Pixmap and that
appears to be on the scanout (i.e. all the updates should be visible).
