error_message

(gui.py:2772): Gdk-ERROR **: The program 'swipe.py' 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 1272 error_code 9 request_code 152 minor_code 9)
  (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.)

Hello @LutzLue, no I did not. This was more of a experiment anyways, just use a GtkStack for a stable implementation.
