Interleaved VBO with mixed types fails on AMD FirePro M5950
Hi Folks,
just spend two days on debugging my code on a customers' HP Elitebook 8560w with AMD FirePro M5950. This GL code worked for ages, on every hardware I came across. It's simple:
Given an interleaved array of positions and texcoords [x0, y0, u0, v0, x1, y1, u1, v1, ...] the following code doesn't work on the Elitebook, if the positions are of type GL_INT and the texcoords are GL_FLOAT:
glBindBuffer( GL_ARRAY_BUFFER, MyVBO );
glVertexPointer( 2, GL_INT, 16, 0 );
glTexCoordPointer( 2, GL_FLOAT, 16, 8 );
No error is generated, but nothing is rendered. After casting the positions to floats and using GL_FLOAT in glVertexPointer it works as expected.
Just wanted to let you know. Maybe some AMD guy should have a look at this.

I would suggest you posting it on AMD's website instead. I don't think anyone at AMD is paid to read this forum.
