New iMac - Scrambled Graphics
I recently purchased a new iMac. The spec is as follows:
Is this an issue other people have encountered? Should I be concerned / ask for a replacement system?

I have the same 2GB card in my new 27" with the 3TB Fusion drive...I haven't encountered any such issue...But if it's just a flicker when loading I wouldn't be unduly concerned, just keep an eye on it..If it starts happening in Apps then you might need a replacement, but for now I don't think it's major.

I have noticed similar artefacts on a number of different Macs. It seems that when an OpenGL view is initialised, it will allocate a random chunk of VRAM for its framebuffer and under certain circumstances you will see the 'old' content of that chunk. It might be some random noise or old images of windows/window parts. Anyway, I don't think there is any reason to worry.
