The test case is still failing as of Chromium #613020 (see the "Detailed report" link in #0) and the clang roll was reverted in #612687, so it's not related to the roll. I think someone familiar with ash needs to take a look.

This was probably the improper cast of WindowPreviewView to WindowMirrorView. This should be fixed by Daisy's patch at [1]. [1] https://chromium-review.googlesource.com/c/chromium/src/+/1370321
