Same thing happens to Epiphany. Seems to be a Cairo bug/issue?

Status in Ubuntu GNOME: New Status in gnome-system-monitor package in Ubuntu: Confirmed Bug description: Upon launching a game that runs the Unity Game Engine, gnome-system- monitor will SIGTRAP with the following output: brandon@Desktop:~$ gnome-system-monitor ** (gnome-system-monitor:6342): WARNING **: SELinux was found but is not enabled. (gnome-system-monitor:6342): Gdk-ERROR **: The program 'gnome-system-monitor' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 68264 error_code 8 request_code 62 (core protocol) 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 GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
