Hi,

I can also confirm this bug running ubuntu 10.4, Sun Java 1.6.0_20-b02, ATI Radeon HD 4350.

Eclipse often freezes up for a couple of seconds, using 100% CPU, and Java2D animation is always jerky / choppy.

Strangely enough, it seems that moving the mouse around over the window seems to smooth out the animation problems, found this as a recommendation to fix animation at (http://forums.java.net/jive/thread.jspa?threadID=38821&tstart=0)

They also recommend using Toolkit.getDefaultToolkit().sync(); in the animation loop to try and sync every frame. Unfortunately this does not seem to work, as also confirmed by several people at (http://kenai.com/jira/browse/TRIDENT-2).
