GPU Caps Viewer has several OpenGL demos. one of the demo is GL 2.1 - Vertex
Displacement Mapping, which is used run fine with Mesa 10 stable but now
regressed in mesa master.
the program can be run by wine.
All the demos emitting the following in the terminal:

0:6(12): error: value of type vec3 cannot be assigned to variable of type vec4
source:
attribute vec2 position;

void main()
{
texCoords = textureCoords;
gl_Position = vec4(position, 0.0, 1.0);
}
