275.09.07 causes corruption (black areas) when composition is enabled on KDE
Hi, latest driver (275.09.07) shows some issues, at least on my system; basically there is something wrong in updating screen areas. What happens is (as an example) that after screensaver (I use xscreensaver) switch off by moving the mouse or similar actions the screen is not updated and large part of screen remains black. Only moving windows around or resizing them the screen gets updated properly. If I switch desktop effects off, all works fine again.
