Screenshot of the static main menu

Half-Life 2 (running in Wine) has a random vertex corruption. This corruption can be seen in the static main menu(start it with -console) and in-game. The corruption goes away if I modify Wine to always write gl_ClipVertex even if clipping is disabled.

This is interesting particularly because r300g does not support clipping with vertex shaders. It says so on the command line, and in-game rendering and the Wine tests confirm this.
