1192571 - Dragging a youtube tab to another window in e10s mode makes the video go black

Status: RESOLVED FIXED

(Core :: Audio/Video, defect)

Description

[(no longer active)]

STR: Load a youtube video, and drag it either to another window or detach it to make it become its own window.  The video goes black.

Surprisingly, if you drag the tab back to its original window, the video paints correctly again.

This only happens in e10s mode.

I can repro on Mac 10.9.5.  It works on a build from mid July, so it seems it's a recent regression.  I'll track down that regression-window shortly.

Matt could the fix for bug 1061525 have caused this?

Yes, that seems likely.
