It would just be too good to be true if there was one simple patch that
fixes all problems ;-) As you wrote to me in private mail you are
referring to lockup problems and the dark lighting in flightgear.
As to the lighting problem, Brian and I discovered a few months ago that
an uninitialized (random) fourth component of the light source position
can cause large lighting differences between hardware and software TCL.
I made just that mistake :) and Brian pointed it out to me. I had a
short look at an old flight gear source later and the lighting stuff
looked quite messy. I got rather confused by the interaction between
PLib and OpenGL state management and bailed out. Maybe someone more into
flightgear and plib wants to take a closer look at that.
