1. I guess the reason the shadow is black is we don't implement

GL_ARB_shadow_ambient. With the driver which can render the shadow correctly, try to set this environment variable:

MESA_EXTENSION_OVERRIDE=-GL_ARB_shadow_ambient

to temporarily disable GL_ARB_shadow_ambient, and see if the shadow becomes black.

The driver that renders correctly is the proprietary one, which doesn't use Mesa variables.

2. I know of the wireframe issue, it's been bugging me since ever. It can be

seen e.g. in ETQW on the water and in Nexuiz with GLSL enabled. I think it only shows up on R500.

I can also see it in the water in sauerbraten (although it is almost imperceptible there); You can count on me to debug/test that.
