Not sure if anyone else gets it... I have to take a look & see if I undertsand why I get it.
Looks like everyone gets it - glxgears has begin/end pair with only two vertices for a triangle primitive - maybe a bug..
I saw something like this too, when I implemented and debugged the savage fast path. I don't think it's glxgear's fault. More likely a problem further up in the mesa pipeline. (or are you bypassing the pipeline in the r300 driver?) The t_dd_dmatmp.h template ignores extra vertices that don't add up to a whole primitive. I guess you could do the same.
I think we are bypassing it, though I am not really sure. r300 driver does not use any templates - I did not have time to find out how to use those.
Both mga and r200 use them in a different way, mga driver way appears to be simpler, but does not use vertex buffers (at least in a way I can understand), also it looks like mga hardware cannot do all primitives natively, while r300 can.
