ever since I upgrade to tiger on my ibook g4, i've been getting graphics corruption in preview and idvd.
here's a screenshot to show you what i mean. this happens when i open multiple windows in Preview app. some of the windows become corrupted. if i click once in the window it'll refresh and load the proper image, then another window will become corrupted. does anyone else have this problem?
i am using screen spanning hack, but i've uninstalled it and determined it's not the culprit. it happens w/ just using ibook's screen w/o hack, so i don't think it's a vram issue...
