--- Comment #9 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Briefly adding to what Emil said (which I agree with all of):

The one-frame-at-a-time thing... is that flash only, or does it happen
elsewhere? If it's flash-only, I'm inclined to discount it as a flash bug.
Flash has _tons_ of bugs in the video functionality, they only test it directly
with the nvidia implementation, and when it works there they stop. We do not
aim to be bug-for-bug compatible with the nvidia impl.

If the one-frame-at-a-time thing happens elsewhere too, that most probably
points to an interrupt delivery problem. An easy thing to try would be to
disable MSI (boot with nouveau.config=NvMSI=0) which was added with kernel
3.13. If the issue was happening before 3.13, it's something else.
