@Clément Foucault (fclem): mind having a look?

This is because of an optimization. The only way to have correct rendering is to render everything twice. I don't know if we want this? @William Reynish (billreynish) @Brecht Van Lommel (brecht)

I think this is relatively important, overlapping UVs are common.

Is it possible to do this in a single pass with a Z-buffer, drawing selected UVs with a higher Z value?

Yes it is possible. However we need to give up on Antialiasing of the points in this case (which is not really a big deal).
