Issue with ATI radeon 5570 2Gb [10.6.8]

[simon1990]

Hello,

I think there is a problem with my ATI radeon 5570 2Gb running on snow leopard 10.6.8. The graphic card is fully recognized but the dock's magnifying and icons' opening are brokenly and glitchy.

The strange thing is that the problem disappears when I open an application like logic 9 but it returns when I close the application.

I tried to use graphics enabler=yes and graphics enabler=no but the problem remain.

Can you help me? Tell me if you need other informations, thanks

After few days I found the problem. It's a power management issue, infact with "nullcpupowermanagement" kext or without "AppleIntelPowerManagement" kext, graphic is more fluide but on the other hand I lose the sleep function.

Is there a way to fix the power management problem?

I fixed this issue by installing the drivers of my mouse (MadCatz M.M.O.7)
