As you can see on the screenshot, the soldier should carry only one weapon. But on some systems the weapon is drawn using all sprite animation files at once.

Normally it uses just one. This is how the sprite file looks like:

This happens on Radeon x1650 with latest Omega drivers. Any idea how to fix this?

Looks like the rifle is being draw from all the texture space, not only the part where it should be restricted to.

You could draw a quad whose mapping coordinates corresponded to those of the sprite you need at each time.

Yeah that's what I do I just map UV coordinates to the frame. However it doesn't work on that specific system.

Do you use manually coded texture coords or texture matrix? What size is the whole sprite?

The size of the gun sprite is 77x70.
The frame size is 77x14.
I use texture coords in vertices.

The coordinates are calculated from the sprite size.
Based on Texture->getSize().Height

This might be the problem... I remember this function giving different results on some systems. Why would it do that?

probably if you query hardware features on that system you will notice that NQuad textures are not supported. First you must try giving as input a square texture (possibly a power of 2.. so 128x128?)..

Argh, that's probably once more an incomplete NPOT support where either wrapping doesn't work or some other stuff is going on.
What are Omega drivers?

Omega drivers, no idea, I can find out.

Could it a possible fix be a different texture wrapping?

Yes, sometimes certain wrapping modes are not available with NPOT textures. Or the driver did not properly implement all wrapping modes. Just try some others.
