%%%Probably already known, but I couldnt find it in the tracker(although some trouble searching...:-):

To reproduce:

Create a plane
Use the knife tool to cut into a concave shape
Open the UV editor and unwrap(eg project from view)
press n and in Display, enable Draw Faces.

OS Windows 7 x64,
460GTX (301.24 drivers),
Blender Version 2.63 RC1 (x64 build)%%%

%%%I am afraid there's no simple solution to this. The UV editor does not tesselate uvs in UV space for display. Not a show stopper though IMO.%%%

%%%Think i'll agree with Antony here. This issue might only be solved by running UV map tesselation, which isn't so difficult. But it's much more difficult to make this behave fast -- it'll need to implement some UV tesselation cache system, which isn't here yet.
