[fixed,kind of]1.2 slow under Linux with free Radeon drivers

I don't have a Linux box or ati card to test with, but I'm relaying the report and workaround from GFXStyler (reported via IRC)

Try R300_SPAN_DISABLE_LOCKING env var if this hangs.

Apparently installing fglrx fixes the problem

Hmm, similar to the line smoothing flag just disabled. We should make all things toggleable

hybrid => This is a bit offtopic but the smoothing flags really seem to be unstable. I realized that my ATI drivers for Windows are really old (whereas my fglrx on Linux is the last one) which explains why I have all these problems on Windows (unfortunately I can't update them because I have a bloody laptop).
And disabling line smoothing and point smoothing just makes all problems I reported with GLSL disappear so you should really consider not using them by default.
