I poked around a bit on this as it had been bugging me.  Instead of 
trying to fix OpenGL's AA, I added an option to utilize Cairo AA, which 
should provide a much nicer render in Eeschema.  This is too slow for 
complex boards in pcbnew but works nicely with schematics.  You can 
modify the level of AA, with the "High Quality" mode utilizing sub-pixel 
AA.

Let me know if this works any better for you.
