From "Settings > About Chrome"
Application version:
Operating system:

URLs (if applicable):

Steps to reproduce:
(1) Open Youtube on Chrome Tab.
(2) Click on a video and go full screen.
(3) Press the screen lock button on the side.

Expected result: The video on youtube running on full-screen mode can be minimized back to original viewport, and it can be can run again on full-screen mode after going back to the tab which was playing the video.

Actual result: The video screen gets blacked out with audio playing normally. No video output on the screen. The full-screen mode for playing the video presents only a black screen.

I have reproduced the result on the chrome browser and Andriod sandbox.
