fglrx and kwin compositing

Hi!
I've got a problem with kwin's compositing and fglrx. Basically, resizing a window takes about 1-2 seconds. The problem occurs with both the OpenGL and XRender backend. I've tried playing with my xorg.conf file but could not get the problem fixed. I know that I'm not the only one with this problem but I was hoping that some of you might have found a solution.

Edit : Well, it seems that the problem is not related to kwin. I've got the same problem with compiz.

thanks,
Rognon

Re: fglrx and kwin compositing

Your configuration makes not difference at all, in both kwin and compiz. Thanks anyway.
