What is the best way to start a Steam game on a NVIDIA Optimus laptop with Ubuntu 12.04 installed and the latest version of bumblebee installed?

If I call Steam with optirun steam and then choose the game I want to play, I get the following error:

The program 'hl2_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 125 error_code 9 request_code 14 minor_code 0)

  (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.)

If I run steam without the optirun option, I can go a little further into running the game, hearing the starting music on a black screen, but still fails later on in the process.

Should I call the game I want to play with a special optirun command instead of optirun steam?
