test program

glLineStipple gives inconsistent results on my HD 3200, Maybe something is overwriting the PA_SC_LINE_STIPPLE register or register is not properly saved and restored?

attached is a small test program, and the output at different runs.

Comment 3 James Willcox 2010-11-29 08:34:16 UTC 
I have this problem as well on a 785G.  Mesa master as of today, r600c.
Comment 4 Alberto Milone 2011-01-13 09:45:45 UTC 
I'm unable to reproduce the problem with my Radeon HD 4200 with Mesa 7.9~git20100924 and linux 2.6.35 in Ubuntu 10.10. I can reproduce it in Ubuntu 10.04 though.
Comment 5 Jerome Glisse 2011-03-08 09:56:42 UTC 
Does it works better with r600g ?
Comment 6 Dave Airlie 2011-11-06 05:06:37 UTC 
please retry with latest r600g.
Comment 7 Jerome Glisse 2012-02-22 10:02:23 UTC 
Closing, reopen if it's an issue with recent r600g from mesa 8.0 or newer
