I have a  a 8600GT on my desktop, and I don't experience this issue at
all. But, on my laptop which is running the fglrx driver I have the
exact same behavior with konsole (around 5-9sec to resize). Both are
up-to-date Debian Squeeze kde4 (kernel 2.6.30), with the more or less
the same effects enabled, and both with bare xorg.conf, but the laptop
is running Sid xorg and fglrx.
I was thinking it was just a matter of fglrx performing poorly with my
hardware, but your message makes me think there's another problem behind
