Comment 23 for bug 419264

I'm still not certain whether this is going to need a fix in compiz or in something mesa/libdrm/intel-ish, but I've gone ahead and filed the bug upstream with X.org at https://bugs.freedesktop.org/show_bug.cgi?id=23566 and flagged it to our Intel rep. The fact that it showed up after we upped mesa, and goes away after downgrading to 7.5 seems too suspicious for coincidence. (I'd like to hear if this holds true for others.)
