Bug Description

I keep firefox on its own desktop, and switch to it via a keybinding. This problem manifests itself even when switching focus via mouse on the same desktop, though.

Basically every time I come back to firefox, it appears to ignore my input for a good long while. I am not seeing any swapping, and even the mouse cursor does not change in response to hover events.

The effect goes away when I restart the browser, but slowly returns the longer I leave it running.

This only started happening this weekend, and it happens in both unity 2d and 3d.
