<pre>The cause is that replies end up being blocked by the synchronous pageflip used
for the tear free update of the scanout. The solution is obvious, but just
tricky to implement in an efficient manner that also solves the unnecessary
readbacks. If I get it right the extra complexity should help for normal
rendering as well.</pre>
