BTW, at http://www.jvuletich.org/Cuis I uploaded some screen shots of Cuis with and without subpixel AA and at various Display depth, for those too lazy to actually download it.

Not to be nit picking but being it anyway... In the SubPixelAA pictures in the Workspace on top I see white pixels in the f, t, 1, B and s....

I see some artifacts on the subpixel
You are right! It is in the 32bpp image. Of course you don't see those in Squeak, it is a problem of how I saved the PNG file. I fixed it now.
The details... The alpha channel of Display is ignored by VMs. So we don't pay much attention to it, but it usually contains "garbage". This was noted by people using composing window managers in Linux. You see in the png that I evaluated 'Display fixAlpha. PNGReadWriter putForm:...'. That fixed the alpha channel for the whole Display. But it seems that when evaluating, Squeak redered the selected text again, creating the defect you noticed.
