Just got back to my MacBook after it had been asleep for a few minutes. Upon awakening it, I discovered that all shadows of all applications are just displaying as corrupted junk, and all Dock icons are also junked ! Mousing over the Dock with magnification on seems to fix the icons, but there's nothing I can do to fix application shadows.

This is the second time this has happened already - last time I put it down to running Virtue, but I don't think that's the case.

Also, simultaneous with the graphics corruption, system performance has got very laggy. Scrolling is a nightmare, and even typing is laggy.

What's the cause ? Bad graphics card - or maybe bad memory (I know the graphics uses main system memory) ?

I have 2GB of RAM coming in the post, so I"ll see if the problem goes away when it arrives...

    Sounds like you have a bad one, if you can make the graphics go strange every time take it back and ask for a new one.

    It could be bad RAM, take them out and re seat them again, then try one at a time.

    nsnowingYou might want to check out the following thread in the Mac mini forums…

    It seems as though it's a very similar issue with the graphics… apart from the system crashing down around you.

    I have the same issue with my MacBook Pro. I usually just close the lid and let it go back to sleep, then reopen it. That usually solves it.

    I have the same problem....every once in a while it happens...the very same...shady borders...closing the lid or logging out and in fixes it alright.

    I called Applecare and they were very helpful...I talked to two people and one suggested that I reset the PMU by shutting my Macbook down and removing the battery. The next asked me to start up with the first install disk while holding D to run a diagnostic; everything came out fine. He suggested that it might be a ram problem...and that is what I deduced when I launched everything in the dock and watched the glitch appear.

    For all those who claim their macbooks don't have this problem...try to launch every program in your dock....Google Earth seems to help and get back with us.

    Is it possible that maybe Apple didn't ship enough ram with this configuration with this graphics card.

    I've ordered 2 gigs of ram so it might just fix itself....but this could possibly be very bad for Apple....if it turns out that they aren't loading enough ram.

    I get the same problem, and I can reproduce it if I sleep the computer with allot of apps running (the performance gets very slow). I usually force a reset, I forget the key combo, but it forces all the apps closed and resets it, then everything is fine. Sleeping it and opening the lid again never fixed it for me.

    It's only happened twice... but, as it stands, this thing is allot less stable than my Windows XP box :P. Haha, that's a shock for me. Hopefully the 2gb of RAM I'm going to put in it soon will fix the problem. (I'm running 512mb ATM)

    All I can deduce is that it has to do with the dependant graphics card. As the Mac Mini has suffered these problems and it is the only mac that has this card than it must have something to do with it. Also, perhaps with the ram hogging OS X, the cpu didn't have enough ram to share with graphics card so we get this mess....perhaps Apple needs to start the line at 768 mb or 1 gb or ram to fix this problem...or else switch to a graphics card with its own memory.

    The problem Apple has with doing any of these is that it raises the cost of the MacBook. Also, there is a technical reason for doing this. At some point in the not so distant future (within 6-8 months) the vast majority of application will be Univeral binaries. Meaning, Rosetta will not be an issue, nor will it's RAM requirements. In an Intel binary only world the RAM requirements will be the same as PowerPC RAM requirements.

    Apple, for this short period does not want to be setting a precedent for the furture by upping the minimum RAM to 1GB. This then would force their hand into doing it across the board with all model from here on out.

    I think Apple can speak for itself...if they are charging 1500+ for product that I buy and don't guarantee that it will work out of the box...I think there is a problem.

    Now I am not saying this product is entirely worthless or that Apple is not willing to help...but if the only solution to this problem is more ram for the time being...they should do this. There are people who rely on these machines for work and don't want to take time out of their day to restart over and over again when this occurs. I should be able to launch more than 3 apps at a time without this mess....

    In the future they can always move the memory back down...but in this time of transition...I'm sure a little more ram at wholesale price isn't going to hurt that much...especially if it makes their customers happy. I once read that Apple charges 4 times what it takes to make their products....which is fine when the product works...
