How can I check why my software rendering does not do line stipple? You could try it with software mesa and see if it works there. Also, the fallback for r300 only happens if you don't have disable_lowimpact_fallbacks set, so if this is set for whatever reason you will indeed get a solid line. If you set RADEON_DEBUG=fall it should print out a warning if it hits that line stipple fallback
