Hi Sean,
I just double check and the fix is integrated. We are using
our internal J3DGraphics2D test program with GL_EXT_abg disable.
The bug appear in v1.3 beta1 using texture mapping
(i.e. -Dj3d.g2ddrawpixel=false which is default under windows)
but not in v1.3 beta2.
I've a few questions
(1) Is the bug reproducible under v1.3 beta2 DirectX version ?
(2) Is the bug reproducible if you are setting the
flag
Java -Dj3d.g2ddrawpixel=true yourApps
under v1.3 beta2 OpenGL version.
I guess you may encounter a different bug that is not
the same one. Usually if the user did not supply a test
program we would try our best to reproduce it.
To ensure the problem that you mention
resolve in v1.3 release, please send us a test case
to investigate.
Thanks.
- Kelvin
