Can you also reproduce it in the applet demo here?
Yes, I can. I'm running Linux (Ubunt 12.04)
The applet ran with JDK 1.6.0_33 (64 bit)
When using RSTA, I see with problem with JDK 1.7.0_09 (32bit)
So this seems to not be tied to any particular JDK version on Linux.
* I also see the problem on Linux Mint 13 (Maya)
* I don't see the problem on Windows XP
