If I change any video settings in CS, my game restarts, but then the screen is black, or it crashes. It only happens if I am starting the game on the Nvidia card with "primusrun". Should this be reported to the primus bug tracker instead?

Example, after toggling HL models on/off:

World module shutdown.

Server module shutdown.

The program 'hl_linux' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 7207 error_code 9 request_code 153 minor_code 8)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
