Just updated my mac mini to Intrepid RC and java graphics performance has degraded enormously. Working in netbeans causes a 50% (1 of 2 cores) peak every time gui interactions are performed (mostly caused by Xorg). I tried disabling Compiz but that did not help.
Applets have the same problem.
I was thinking about java 6 update 10 but that can not be the cause because I was using the same java version on Hardy. So it must be a change in the Xorg - Java - Intel drivers interaction?

I'm not having any problem on my AMD Athlon(tm) 64 X2 3800+ with a nVidia Corporation NV43 [GeForce 6600 GT] (rev a2).
