Window manager warning: "" found in configuration database is not a valid value for keybinding "toggle_shaded"
The program 'gtk-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 332 error_code 180 request_code 156 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.)
Window manager warning: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.
