Hi Marco, you can find some more information on the "edges glitches" part here:

Although that is something that I want to try and improve in the future I do not expect to be able to work on it for V4, sorry.

Antialiasing for shaded surfaces is still on my list to investigate and may be feasible to add for v4, I will know more when I give it a try. It is still on my remaining investigation list.
