This might have to do with child HWNDs when direct compositing is enabled. kylechar@ can you take a look?

Ping Kyle, any update on this? Is this still an issue?

Comment 3 by kylec...@chromium.org, Jul 26 

Yes, this still happens. I think it's related to  https://crbug.com/791660 .

Comment 4 by kylec...@chromium.org, Aug 15 

I can't reproduce this anymore. I'm not sure what would have fixed it though, which is a bit concerning.

I bisected builds to figure out when this stopped occurring. I found that 93fb1b7fb59d331ae1a64e8bdae0f408890839e5 is where the black window after killing GPU process stopped reproducing. I was also able to verify that change wasn't the actual problem, it just changed the timing enough to cause the race described in  https://crbug.com/791660#c4  to not longer happen regularly.
