I checked the docs and found gl_texture_pile_height, it is set by default to 100 so I lowered to 1. The problem is gone.
I'm sure this affects performance so if the problem is a bug that is fixable that would be great. Any clues? Thanks. Daniel _______________________________________________ fltk-opengl mailing list fltk-opengl@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-opengl
