1083188 - Firefox mixed the content of 2 app tabs

Status: RESOLVED DUPLICATE of bug 1067470

(Core :: Graphics, defect)

Description

[Guilherme Lima]

Attachment: Screenshot

I was on Gmail, then clicked to change to Mozillazine Forums. The app tabs got kind of corrupted, half selected, half not.
Nightly was still showing me the Gmail content, but passing the cursor around, it showed the content of the Mozillazine, but only the links (invalidation?).

I'm on Win7, testing HWA off.
