Hi

It does not work with odd sizes, does it?

Edit.: As far as I know, using odd sizes might cause some trouble in OpenGL, it is not a bug of JOGL:

hi,

i verified this...
the texture dimensions must be a multiple of 4 or equal 1.

boolean dimOK = dim == 1 || (dim % 4) == 0;

thanks for your help!

You're welcome. You provided some precise data, it was helpful to understand what was happening, that's nice.
