There is a bad redisplay problem for large (greater than around 1000 lines) text windows using a TextArea (or a Swing JTextPane). I have the feeling it is specific to the Intel driver.
The problem persists in Rawhide.
It seems to be a known problem in the EXA driver: http://bugs.sun.com/view_bug.do?bug_id=6776352
Switching to the XAA driver (using Option "AccelMethod" "XAA" in xorg.conf), fixes the text redisplay problem, but causes worse problems, making the desktop unusable (at least on F10).
I did find a workable workaround from the above bug report: Start up java with the -Dsun.java2d.pmoffscreen=false flag. This makes NetBeans much less annoying!
Hopefully Intel will fix the driver soon - it would be nice to get a less buggy driver for F11.
