Thanks, Boris. I had already seen that blog and understand that what this might be is just a refresh time artifact. However surely some sort of delta update mechanism or double buffering technique would reduce the definite two stage clear/redraw that one sees. You're either not changing so many pixels or you're only doing one screen refresh instead of the whole screen twice. I was just wondering whether this is something which can be improved in software/firmware or whether it was an artefact one has to live with.

zdravstvuitye Tovarish - I've read your other posts. Have you actually dismantled/rooted the Edge?. I remember you saying that the 16 levels of grey is potentially unlockable. Do you think that future software updates might improve things? I'm sure once the SDK goes public we'll see some great things.
