I think I found the problem. The hardware already makes the right decision
based on the FACE_bit. This code in r700UpdatePolygonMode actually reverses it
when using clockwise winding:
if (ctx-Polygon.FrontFace == GL_CCW) {
f = ctx-Polygon.FrontMode;
b = ctx-Polygon.BackMode;
} else {
f = ctx-Polygon.BackMode;
b = ctx-Polygon.FrontMode;
}
Changing it to:
f = ctx-Polygon.FrontMode;
b = ctx-Polygon.BackMode;
seems to fix it and render everything correctly.

It will render a solid triangle while the software renderer renders an outline triangle. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
