Comment 240 for bug 1140716

Hmm, it really shouldn't be that noticeable after a gpu hang... unless you are using a compositor? Certain operations will be unavailable (accelerated GL, vsync, etc), but for everything else it should fallback to a shadow buffer and for typical rendering although it may be an order of magnitude slower it shouldn't actually impact upon latency. Moving windows and scrolling should still be crisp. So if you can, please grab a 'sudo perf record -f -g -a' after such an event.
