With any persona on(haven't noticed without personas) I get black boxes on the title bar randomly while i'm browsing the web, if i choose a new tab the background of the title turn normal but the black box stays where there is no title. hiding the window and restoring it works to get rid of the box but after a while it appear again. (I'm using the new panorama heavily)

Reproducible: Sometimes

Steps to Reproduce:
1.Install a persona
2.open multiple tabs
3.use the tabs as usual and it appears randomly
Actual Results:  
Black boxes appeared on the title bar at random places

Expected Results:  
Not display any black boxes
