Basically, use gdb to set a breakpoint in _mesa_meta_DrawPixels() then go step by step to see where 'fallback = GL_TRUE' is getting hit. To set a breakpoint: "break _mesa_meta_DrawPixels()" To step one instruction: "s" or "step" When you find the point where fallback = GL_TRUE is set, note the current line and try to print some of the variables in the conditionals. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
