adding RB-label as this is recent regression, pleas change if required.

Just to update, This issue is observed on latest canary M52-52.0.2713.0 as well. Observed a while flickering screen at the time entering to fullscreen.

Is this only reproducible via Vudu? Do other videos such as Netflix work?

Just to update: Able to repro this issue on MAC (10.11.4) for Latest Canary Version - 52.0.2715.0

Temporary fix for "white patch" fullscreen regression on OSX

This is a partial revert of https://codereview.chromium.org/1790663003
which introduced the bug. While it doesn't fix the regression in popups,
it will at least fix it for a normal browser window which is exposed to
more users.

With response to comment #17:

Above issue is not reproducible on latest canary version i.e 52.0.2738.0 on MAC OS X 10.11.4 

@spqchan: Request you to look into this issue as per the comments #17 & 18

Thank you.

#19 Acknowledged. Currently working on a longer term solution to replace the short term one.

Verified the issue on Mac OS 10.11.5 using chrome latest Beta M51-51.0.2704.54. No white patches observed on viewing the vudu videos in full screen mode. Hence adding TE-Verified label.

Thanks!
