Comment 20 for bug 288650

It is related to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6708580 as well as the entry on my blog. Its caused by switching to EXA by default in later Intel drivers, as well as poor X(Shm)GetImage performance.
This problem occurs when switching between hw-accaleration and software-rendering.

I contributed a small fix to completly disable hw accaleration as a workarround which should avoid those worst-cases, it has been integrated in JDK6u12b03 pre-release, would be great if you could give it a try: http://download.java.net/jdk6/binaries/

A long-term solution would be to use the RENDER api, I am currently working on a java2d backend based on RENDER. You can find some information about it on my blog http://linuxhippy.blogspot.com/ as well as http://78.31.67.79:8080/jxrender/.
