[Pkg-fglrx-devel] Bug#634036: [fglrx-driver] with fglrx-driver Xorg eats 15-20% of CPU core

[ras]

Package: fglrx-driver
Version: 1:11-6-2
Severity: normal

When fglrx-driver used as a display driver, Xorg process is constantly eating 15-20% of CPU core,
as shown by top, even while there's no display activity. If xserver-xorg-video-radeon is used instead,
Xorg uses only 2-5% of a CPU. I tried it with the dist kernel and custom kernels, results are the same.
I use KDE4 with effects turned off.
