anyhow, probably i'll do that tomorrow:
how about an environment variable "GEM_RECTANGLE_TEXTURE" which could be

Is this just for Linux?  The problem doesn't exist on OSX and I'm not sure how many people know how to adjust environment variables under Windows.  I have never seen much performance difference between the two modes under Windows either.

Can you try a GLEW test for this?  I know we have talked about using GLEW for a long time, and this seems like a good one to start with.
