I played a little bit more with it, and I think the best solution is to 
completely disable subpixel rendering for translucent text. To do this, 
go back to the old version of the method, (dated on 2009) and replace this :

        (Preferences subPixelRenderFonts and: [ foregroundColor = Color 
black or: [ Preferences subPixelRenderColorFonts ]]) ifTrue: [

by this:

        (Preferences subPixelRenderFonts and: [ foregroundColor = Color 
black or: [ Preferences subPixelRenderColorFonts and: [foregroundColor 
isOpaque]]]) ifTrue: [


This makes almost opaque colors (alpha > 0.9) look much better.

Cheers,
