Version:            (using KDE 4.2.2)

Hello,

resize window or maximalize with composite function enabled is very very slow. When composite is disabled everything works OK. 

Distro : Archlinux 
KDE version : 4.2.2
VGA : ATI x1400
VGA Drivers : radeon (with catalyst driver same problem)
Xserver : X.Org X Server 1.5.3
HW : Genuine Intel(R) CPU T2500  @ 2.00GHz, 1GB RAM

Hello,

adding option "AccelMethod" "EXA" for radeon driver (in xorg.conf) solved this problem. Resizing is very fast now.

But, in menus with icons I see some icons broken (some graphical glitches). This maybe caused Qt 4.5 or radeon driver

Driver problems.
