I've just installed 10.04 64bit on my iMac 27" i7 and before fighting with keyboard, mouse, audio,... I'd like to share with you a strange behavior of the screen refresh speed, color depth and/or maybe a performance issue with the ATI. It's happening with all the resolutions and I don't appreciate it on OSX. The windows borders are "cut" when moving or scaling them, the login screen seems to have a low color depth (as banding issues) and it appears slowly from top to bottom of the screen... for example, when I open the synaptic and the system ask for the password, I can see a very slow fading effect to dark screen...
I've made a full update then install the ATI proprietary drivers (from the ubuntu repositories). Basically I'd love to hear that my problem is a driver issue but it seems that 10.04 comes with the very last drivers from ATI.
Does someone experience such a behavior?
Does somebody know how to enhance it?
PS: Hope the attached "test.tar.gz" helps to understand better.
