Does it make a difference if you're using Fl_Window vs.
Fl_Double_Window?
Sometimes double buffering can limit color resolution, and possibly
something in FLTK changed in the way it initializes that affects
openGL in this way that we can identify and fix.
Also, if you can provide a small FLTK opengl program that shows the
problem,
that would help.
I'm assuming you're using opengl calls to read back the color depth
and getting 5bit instead of 8bit. Giving us a /small/ program that
shows this (ie. sets up opengl and prints the bit depth values to the
console)
would really help us track it down.
