That commit just disabled an optimization in some cases where it wasn't safe to do. I suppose it may be interesting to see if disabling the entire else-if block that patch touches makes it better or worse. Bryan Cain is much more familiar with the glsl-to-tgsi code than I am though. The typical way to debug things like this is to figure out which shader is responsible for drawing the geometry in question, using something like apitrace or your own debug hacks, and then comparing the GLSL with what gets sent to hardware (and any intermediates). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
