It seems unlikely because the test case doesn't mention YUV or video. Is there any way to bisect it down further automatically?

Hi Chris,

I really have no idea what to do about this. I'm pretty certain that it's not my CL, and I suspect a driver bug, but I can't reproduce this at all on any machines that I have access to.

Yeah, GPU crash noise -- it looks like clusterfuzz cleared this up anyway. 

This bug has been closed for more than 14 weeks. Removing security view restrictions.
