Okay... could you set the value of testRender/capt to some directory with lots of free space and press 'k'? It'll record PPM-format screenshots... then send the appropriate frame(s) to me, preferrably as PNG or JPG. :) I *think* I know what you're talking about (I think I've seen something similar on some builds of r100) - sometimes it skips over a few vertices while playing the displaylist and so the surface gets "streched" out - but I'd like to see it myself to be sure. A good scene for testing that particular failure mode is scenes/test6, because the main object in it has a shape which makes those errors quite obvious. :) > > > > Also, if whoever it was who posted that screenshot could change the Solace > > > > setting of GL_draw_method to 0 (which switches to immediate mode rendering > > > > rather than using vertex arrays) and see if that continues with the > > > > funkiness, that would be another useful data point. :) > > > > > > Switching the GL_draw_method to 1 gave me ... from what I can tell perfect > > > rendering ... well ... at least no flickers. > > > > Huh. > > Oops - mistype.

Does it still happen if you set the value of GL_dlistMax to 0? -- http://trikuare.cx ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
