I'm running a DP2.5 G5 with a 6800U and a 9200PCI.. 4 monitors.



whenever, I zoom in on a really large picture, preview displays nothing but grey.



It's so borked it will even let me take a screen shot of it:



Here is an animated gif of the problem.. it works fine, then I zoom in.

    You're exceeding the total memory of the GPU by zooming in.



    Zooming scales up the entire canvas, then clips to a viewport. So when you zoom a 1000x1000 image 2x, you use 4 times the graphics memory.



    Try it on the graphics card with the most memory.

    Thanks.. that actually makes sense.



    Unfortunately, no matter which monitor(s) I use I still can't view some images, even at their actual size.



    I guess I'll just use graphic converter.

    Nice advice, was the solution on a friends setup.

    Btw, you seem to be quite ...er... quiet about this

    whole Apple-Intel Fuzz.

    Since i honestly respect you very much, - although i had

    my difficulties to understand your intensity sometimes -

    (which i still don't fully understand, which is a good thing imho)

    i appreciate your opinions pretty much on

    this subject. Care to share?



    best

    While not really the thread for it, here's a quickie:



    Don't Panic. It probably won't mean much of anything to the consumer, I think it sounds like the right thing to do, and frankly, I'm more thrilled about the possibilities five years down the road than I am with the imminent Intel switch. Once developers are trained to think in Universal Binaries, moving to any platform gcc supports becomes a piece of cake. We could see MacOS X popping up in *very* unexpected places. I'm thrilled.
