%%%Windows 7, 64 bit

After dissolving some faces of a mesh (subdivided plane for example) and uw unwrapping it the uv unwrap shows strange results.

to reproduce the problem:

Add a plane (top view)
Subdivide it 4 times
Select faces (circle select, not a regtanguar region)
uv unwrap
see the result

Looks like a problem with dissolve faces or uv unwrap or bmesh.%%%

%%%Actually it's a problem with concave ngons in the image editor. This is not a bug actually but a rendering issue related to the fact that we don't tesselate polygons in the uv editor. It doesn't influence the result on your mesh in the 3D view or during rendering though. Closing as TODO.%%%
