Bug#979116: xfwm4: reliable crash on various window states (BadWindow (invalid Window parameter))

[Peter Gervai <grin@grin.hu>]

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


Probably fixed in https://gitlab.xfce.org/xfce/xfwm4/-/merge_requests/18
