Correct selection
When selecting faces in K-3D, selections are fine in Mesa 7.0.1, but seem to go
"through" the object in 7.0.3 (as obtained from ubuntu 8.04). The problem still
appeared in the GIT version obtained a few days ago. The 7.0.1 shows correct
behavior, resulting in the front face being selected (red) when it is clicked.
Doing the same operation in 7.0.3 (second screenshot) results in the bottom
face being selected, even though the front face was clicked. At the moment of
the selection click, the bottom face was behind the front face. It appears as
though when in GL_SELECT mode, Mesa gets the depth order wrong.
THe bug appears both in the VBO and non-VBO code for drawing faces. Selection
in K-3D happens in GL_SELECT mode.
Hardware is an intel graphics chip:
