Bug 29054

Forwarding this bug from Ubuntu reporter Kees Cook:

[Problem]
I've noticed that a number of SDL applications do not animate any more when run under compiz.  Attaching an example that shows this.  (It should animate forever, but under current compiz (i915 driver drm) for me, it will hang immediately or after a few seconds.)

Possibly this is related to or a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=28573
