This is exactly what I see on windows, and what is expected. Thanks for confirming.

Indeed strange. Possibly a problem with GLUT. Could you try with
freeGLUT? Michalis has supplied a patch to support freeGLUT more easy
which was committed recently.

For those interested, I am working on a canvas class for OpenGL that
descends from TFPCustomCanvas. You can find the sources here:
I also created a TGLFreeTypeFont which draws FreeType fonts to the GL
context. This is all part of a new widget set with a dependency on
OpenGL and FreeType only.
