Attachment: disappeared tiles in toolbar menu

In Firefox 45.0 on Linux64 (Xubuntu 15.10), moving the mouse over tiles in the toolbar menu makes them disappear; see attached screenshot.

The problem started with Nightly from November 12.

I can reproduce this too in Firefox 45 Nightly on Debian stretch / amd64.  It also affects doorhanger popups.

[Tracking Requested - why for this release]: Serious user-visible regression in Firefox 45 for Linux.

I can't reproduce this in a VM with Ubuntu 15.10 & GTK 3.16.7. Matt said on IRC that he's on GTK 3.18.2. Markus, what version are you on? |dpkg -l libgtk-3-0|

Need a non-compositing window manager to reproduce (or one that allows compositing to be disabled).

Bug 1210560 is a very likely suspect.
