Apologies for the bad example. Here is a better one (see attached zip). This example demonstrates something wrong with the blending of vertex colours. After running the demo, see lines 79-87 in MainWindow.axaml.cs

The problem seems to occur when the vertex colour alpha is less than one and the rgb values are not black.

   

   

Also in the screenshot you attached in your previous post, half of the circle is missing behind the rectangle. This is an instance of the transparency sorting issues which we emailed you about.

Good luck tracking down these bugs and keep up the great work!
