Fuzzy/blurry Firefox icon when alt-tabbing in various WMs

[Alexey Dokuchaev]

Hi there,

For quite a while (at least several months) I'm observing the bug which
pretty much looks like this one reported upstream back in 2008:

	https://bugzilla.mozilla.org/show_bug.cgi?id=413293

I'm running firefox-esr-24.7.0,1 and its icon looks blurry while cycling
through windows (with Alt-Tab) under both Openbox and Sawfish.

Did anyone observe this recently?  Any idea what might be causing it?
