I highly suspect this is the fullscreen feature issue but not meida specific. can you try this two things: 1) play any video on www.abcnews.com, the video on this site uses flash, please see if this issue repro. 2) navigate to any plain site, e.g www.google.com, use F11 to switch the whole Chrome window to fullscreen. 
do you see the same problem?

Good afternoon,

I've tried both options requested and have the same problem on both. There
are several sites that cause this issue including Netflix and YouTube.

André

Please note that I've tried this on another computer and still have the
same issue.  This seems to happen always on a second monitor without a
toolbar.

André

for the bug to occur, the browser window must be maximized on a display that doesn't have a taskbar on it

Why is this still unconfirmed? I get this too...

This looks like issue 635370. If so, maybe you can help them pin down the conditions where this shows up.
