Hello Gentlemen,
I observed that my code runs fine on NVidia 8000 series and recent ATI cards. Due to an array of uniforms within my fragment shader it’s not compatible to NVidia 7000 series and older, but that’s not the question. Important is, it runs on both NVidia and ATI “state of the art” cards.
I stick to openGL 2.0 (and GLSL 1.2). Most objects I render are GL_QUADs (and some TRIANGLES, very few though (see the sphere below)). A friend of mine has problems showing the QUADS, the TRIANGLES however show correctly.
Let me start with some pictures:
It should look like this:

but with him, it looks like this:

He uses an Asus Nvidia ENGT 240.
It looks like the upper-right triangle of each quad is correct, the lower left however completely distorted. Does anybody have an idea whether this is a known problem with QUADs?
Thanks to all! Cheers, J
