962342 - Random gray box appears at top-left

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[wishfish37]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140120030202

Steps to reproduce:

The bug started to happen in Aurora when I was downloading multiple files and switching between desktops in OSX Mavericks. (Note: It happens very, very rarely.)


Actual results:

A gray box appeared (with black borders on the top and left edges) in the top-left of the screen, obscuring the forward/back button and a little of the page.


Expected results:

Nothing should have happened, and the top-left should have stayed unobscured.

I tried to reproduce a few times on two machines, did not see anything wrong with Aurora 28 (2014-01-21). 
A screenshot and a way to reproduce it constantly would be nice.
Did the gray box appeared and disappeared?
