There are different scenarios where we'd like to use llvmpipe, some with some without shaders, some with some without textures. All these scenarios suffer more or less from the behavior I mentioned before.
I already tried to disable VBOs and use Display Lists instead, but there was no positive effect.

I've chosen two small setups without shaders for you. I will send the traces in an extra email...

Thanks a lot and kind regards,
