So I was testing out the optimization of my map, when the mat_wireframe command produced this strange effect. I double checked that everything was good on hammer, went back, and still saw the bug. Then I went on an official map (cp_dustbowl), and saw the same thing. If anyone could provide some insight, it would be greatly appreciated.

Are you on MacOS by any chance? Or in any other way running the game on OpenGL? Because this is what happened to me when I was still running the game under MacOS. Went away when I switched to Windows (which runs DX9)
