Intel driver - Dual head and 2D performance

[Clemens Eisserer]

Hi,

It could be you are runnig into bug
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6708580
I wrote a small patch which has been integrated into JDK6u12, which
reverts to software-only rendering in the case EXA is used.
So, does the problem also happen with JDK6u12?
