Snow Leopard: annoying black frames around window borders
You know how popular wisdom dictates never to upgrade too quickly? Well I completely ignored that, upgraded my MacBook to Snow Leopard 10.6.1 and am now paying the price.
While the upgrade was rather quick (30 mins) and painless, I have had to deal with several toothing problems in Snow Leopard, or should I say Slow Leopard?
Several days after the upgrade, I noticed a general systemwide sluggishness. Applications launched slowly, screen effects lost their smoothness and suffered a lot of skipping. And strange artifacts would appear on the screen and not go away until I restarted.
Luckily, I was able to find the source of the sluggishness today. It turned out to be GeekTool version 2, this caused my CPU usage to remain between 60% to 70% constantly. I have since removed GeekTool and all is well again.
Now the remaining problems are black frames that appear around window borders where the shadows should be, and weird blocks that appear in the menu bar.
I noticed that these only appear after I have used 3d applications such as Maya. Only a restart will get rid of them.
Anyone else notice this?

Yes. Windows are quitting while i’m working in them and i’ve a black border around anything that’s selected. Shutting down always freezes. Never any help from apple:( It’s like dealing with Microsoft.

I’m having the same problem.
Since I’ve installed Qt (qt.nokia.com/) i’m having the same problem as you, and the last time it happend I was compiling linux kernel in ubuntu (using parallels).
It’s f*** annoying.
hope to see 10.6.2 fix this.

@Celso Dantas, @andy bird,
I have the feeling this only happens when I use applications that require 3d. Can you conform? What hardware are you using ?
