The claim that I don't experience any problems was premature. I'm getting
kernel warnings like the ones below now. I only used the intel driver with SNA
for a few days before opening this bug and I've never seen warnings like these
before using UXA.

I also noticed that I sometimes get graphical corruptions in firefox when I use
firefox's hardware acceleration. "GPU Accelerated Windows = 1/1 OpenGL (OMTC)"
in about:support. It's easy to reproduce by opening any page, selecting some
text and then deselecting it. Firefox then needs to redraw the area with the
text but this sometimes doesn't happen and the text area is left blank. It
happens rarely unless there is another opengl windows displayed at the same
time like mpv or glxgears.

I'm guessing missing page flips is more visible in firefox since it only do the
painting once instead of continuously paining new frames.

I'm using the same setup as before but with kernel-4.4.55 now
