Bug#255192: me too

[Ari Pollak]

I should note that I'm seeing this behavior under openbox & -5 as well. 
I hadn't made the correlation between the new version of X and the 
problem, I originally thought it was just an openbox problem. It seems 
that Alt-tab works fine when only pressing it once, but holding down Alt 
and pressing Tab multiple time results in a very weird focus state.
