Same issue here,

We use robust predicates for doing geometrical operations
on the 2D mesh, so we should certainly be able to do better.
I'll have a look at that whan I have time.
For the "graphical issue", the strange behavior is principally due to
the way
we use graphics : the zoom exceeds the resolution of the viewport. There
again,
we should be able to do better. So, what you see is NOT what you get.
