When I use OpenGL at anything close to full-screen resolution, rendering, audio, and processing begin to stutter -- freezing for about a second at a time. kern.log reports:

[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 247635, at 247635], missed IRQ?

...once for each "stutter" event.
