When my operating system in the mode of normal , gxine works well. However, if I change the mode to SMP, and try to  switch the gxine to fullscreen mode, it crashed  at once.

The printed messages is as follows:

The program 'gxine-ui' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 140 error_code 8 request_code 42 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.)

Who can tell me how to fix it .  Thanks a lot .
