Thanks!
I checked out the plib cvs and built fgfs, which made me to change
GUI/dialog.c a bit but it's OK.
I compiled everything and ran it.... finding the same rectangle... sigh.

You're welcome and thanks for the report. it helps me a lot!
What you said is exactly the same as I see here, so this is not the
hardware specific problem.
Now I'm searching a target to lock on. so let me give some more time ;-)

I really appreciate your help. I've read SimGear / PLIB source and
now have the same opinion.
This rendering is done at simgear/scene/sky/oursun.cxx, especially in
halo related methods / funcs.
Weird thing about this is that it draws the sun as almost big solid
color rectangle.
As two different versions of PLIB have the same result, I think it
has something to do with SimGear.
I'm changing some code so I can try and error about this.
Or should I try another version of SimGear?
