You can try setting the disable_lowimpact_fallbacks driconf option to false. 
This will make the driver use software rendering for certain operations that 
are not supported well. I don't really believe that this option is the 
problem, but it can't hurt to make sure.

Apart from that, I'm afraid you will probably have to dig into how exactly 
Blender renders its menus. Which OpenGL features are used, what are the state 
settings, etc. At least Blender is open source...
