iTunes Visualizer/Core Animation Issues

[CJM]

Hey, I don't know if anyone else has this problem, but I think that, since Leopard 10.5.1 arrived, Core Animation has been acting very strangely.

There's some grey area around the edges of some effects and this occurs in the Arabesque screensaver, too.

Stix behaves even stranger.

These aren't my screenshots, but I get the exact same effect.

Found a thread on the Apple forums; Here. But there're no useful posts, so I was hoping someone here could help? 🙂 Running a C2D intel iMac, with that trusty card, 🙄 the ATi x1600.

Thanks in advance 😉

Learn to resize images!! They took so long to load.

Not installed 10.5.2 and the Graphics Update?

Sorry... they're direct links, should've made them optional I guess.

And nope, the updates haven't fixed the issue. Most perplexing.

The problem still persists 🙁

Bump...

Problem still exists in 10.5.3. Edited original post.

From the Apple Discussion forums, there seems to be a workaround.

Turns out the problem is related to colour profiling. Here's a quote from user Austco who managed to discover this;

I've done a little more investigating and, yes, this definitely seems to be caused at least in part by the color profiles.

Program launched with color profiles set as sRGB IEC61966-2.1:
iTunes visualizers rendered incorrectly as shown above.
Quartz Composer renders compositions incorrectly.

Program launched with color profiles set as default on each monitor(Dell 2005FPW, 'iMac'):
itunes quartz visualizer renders correctly.
Quartz Composer renders correctly.

So, there you go, just my findings; I can change my color profile to whatever I wish as long as I have my default color profiles selected first(no reboot needed, I just have to make sure its selected when I start the program). After launching the program I can switch back to sRGB IEC61966-2.1, and they work fine.

So is this hardware or software related? I'm intrigued. The fix works, but it's an annoying thing to do.
