Package: xfwm4 Version: 4.16.0-1 Severity: normal Tags: upstream (xfwm4:24127): Gdk-ERROR **: 22:58:21.636: The program 'xfwm4' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 92823 error_code 3 request_code 20 (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.) Trace/breakpoint trap
