the problem when running the node rviz
when I run the node "rviz" in the comamnd line like this:rosrun rviz rviz It shows as below:
The program 'rviz' 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 21 error_code 9 request_code 55 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.)
Is there problems with the node "rviz" or something wrong with my PC?
