I went crazy with compizconfig a few weeks ago, figured this one out: blurring alpha channels :P

I'll pull my config out sometime but I got it to work on the gksu and login/logout windows I love eye candy

i am a fan as well, but some i find distracting.

I turn off wobbly windows and actually I prefer turning off the cube and using the wall and expo instead

her windows to stay calm

the same way
