I got a couple of flickers on the right side of the middle sphere using your default radeon registry file. When I used just the plain default registry file I got quite a few more flickers in the cartoonish sphere and the thingie on the right side. > 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. -- //========================================================\\ || D.
