I think it's just this commit, with more confidence as sees it as well.

I was a bit off llvm head when I first saw it, updated to head in case
it changed things - hit the assert bug, found and reverted that commit.

Valley, is normally OK for me. Tricky to get a screen shot as the
artifacts are single frame flashes - though they do repeat. Other scenes
seem to have less noticeable ones than this from scene 2.

Ignore image quality - this is a shot from a paused x11grab h264
ultrafast preset compressed video made with ffmpeg.
