This is my first post on this forum so welcome to everybody.

My ATI x1600 video card is problem which I can't solve by only reading this or insanelymac forum.
After instalation like most I've got 1024x768 res but I've got problem when I move window (look picture1) or scroll something. I've tried to install with Natit.kext or ATIinject way but after it GUI not loads (screen only blinks, system loads farther but I only can see booting white strings.) Anybody got this card working on Zephyroths rev 1?
Any ideas?

My specs:
Benq P52eg
Sempron 3400 (32bit SSE2,SSE3)
ATI SB450, RX485
ALC262 audio
ATI x1600 mobility 256MB

Small update: I checked on safe mode and it seems that this problem doesn't appear there, so maybe I've got same unnecessary kexts which are doing bad job?
