The test case looks simple, and I'm not aware of any bugs that should cause that to break in current master (although there was last week). I'll take this and test tomorrow on current master, as I suspect it may already be fixed, or something very simple.

Same regression range and fixed in servo/webrender#3029:
When making a Twitter video fullscreen there are multiple vertical black stripes at the top and bottom.
