Slow X after kernel update to 2.6.27.39 [SOLVED]

http://forums.opensuse.org – As the title says. System is openSUSE 11.1 running KDE3.5 with KDE4.3 also installed to use desktop effects in KDE3.5. After update X uses 90% CPU to scroll down a page in FF, OOo or even in text editor, either with KWin and KWin4. With KWin4 desktop effects can't be enabled in system config. From Xorg.conf: Code: Section "Device"   BoardName    "ATI Radeon HD 3200 Graphics"   Driver      "fglrx"   Identifier  "Device[0]"   Option      "XAANoOffscreenPixmaps" "true"   Option      "Capabilities" "0x00000000"   Option      "OpenGLOverlay" "off"   Option      "FSAAScale" "0"   Option      "FSAAEnable" "off"   Option      "VideoOverlay" "on"   Screen      0   VendorName  "ATI" Rolling back to kernel 2.6.27.37 fixed the problem.
