Okay, here's an odd one. I was able to reproduce this twice with entirely
different sets of files.
I was attempting to open a large number of pictures simultaneously. Using the
Finder, I selected what I wanted to open (between 600 and 1100 images) and hit
Cmd-O. The pictures began to open one by one as expected in Preview.
After about 300 pictures or so (not sure on the exact count since there's no
real way to keep track), my video became very distorted - windows would no
longer draw their contents and were replaced by large black areas, various
screen elements would appear to move to another location, etc. The mouse cursor
still displayed fine, and while the system allowed me to open menus or interact
with the dock, I was flying blind and couldn't do anything because the display
was not rendering anything correctly. Sleeping the system and waking it up made
no difference and I had to either do a hard shutdown or use Ctrl + Cmd + Eject
to reboot the system cleanly. The problem persisted even after all files had
been opened. Opening the files individually or in smaller groups yielded no
problems.
I'm seeing this on a 2.8GHz quad-core Mac Pro (2008), 10.6.4, 16GB RAM, nVidia
GeForce 8800 GT, 64-bit kernel. I've experienced absolutely zero video problems
with this system outside of this issue, so I don't think it's hardware.
Anyone with a bit of spare time and a Mac with a lot of RAM care to try to
reproduce this?
