--- Comment #10 from Pekka Paalanen <ppaalanen at gmail.com> ---
weston-simple-egl is also extremely fast to render (one triangle!), it doesn't
put any load on the GPU. If you don't throttle it at all, on my intel desktop
it runs at 12000 fps in its default size. So it makes sense it cannot reproduce
the problem, because it cannot block the compositor in its GPU task.

Until we can have the GPU preempted when the compositor's high-priority GPU job
becomes runnable, I don't think the situation can get any better for abusive
(SwapInterval=0) applications.
