It's hilarious that Compiz still doesn't know how to resize windows. Didn't dragging the outline of a window go away in the mid-90s. (yes, I know that there are esoteric ways of fixing this on some machines but enabled by default)
It also consistently fouls up video playback, even on Intrepid and Fedora 10.
I guess the one good thing about Compiz is how easy it is to turn off.
