Mike: Big problems with the 20" iMac with the 256 video ram upgrade.A french user has contacted us to collect information, he is supposed to receive an iMacIntel 20" with the 256MB VRAM option, and he is quite stress about this problem recently identified. We do not know if this problem is also affecting European users. For once, it could be a good point to be only served after USA ;)
Everyone is suffering from video "tearing"... Steve: it only affects iMacIntel 20" featuring the 256MB VRAM BTO... The tearing issue is mostly visible in Front Row and with some other applications.
There is an dedicated subject on Apple's forum:

A video posted by one of the Apple's forum members is showing quite well how disturbing and annoying this "tearing issue" can be. Please let us know if you have a similar problem with your iMacIntel in order for us to get an idea of the impact of this problem, and its geographical spreading.
