Hi Raj,
Looks like the texture transformation matrix did not reset
correctly, you can try
java -Dj3d.g2ddrawpixel=true yourapplication
to force rendering Text2D without using Texture mapping
(work in OGL version only) to see if the problem is gone.
However, we need your test program in order for
us to get it fix in the next beta2 release.
Thanks for your bug report.
