Title:
  xfwm4 crashed with signal 5 in _XReply()

Status in xfwm4 package in Ubuntu:
  Fix Released
Status in xfwm4 source package in Focal:
  In Progress
Status in xfwm4 source package in Groovy:
  Fix Released

Bug description:
  [Impact]

   * Some client applications crash when closing a dialog with the Xfwm4
  compositor off.

  [Test Plan]

   * Disable the Xfwm4 compositor. Settings Manager > Window Manager
  Tweaks > Compositor > Toggle off "Enable Display Compositing".

   * Open Catfish.

   * Open the About dialog.

   * Close the About dialog.

   * Catfish crashes.

   * Once fixes, Catfish will no longer crash.

  [Where problems could occur]

   * Regression potential should be relatively low, as the release
  between 4.14.1 and 4.14.5 are bug releases.

   * With window managers, some changes could lead to different behavior
  and other broken displays. Non-AMD graphics users should also test for
  regressions.

  [Other Info]
   
   * Please see the Xfwm4 release notes for changes between 4.14.1 and 4.14.5: https://gitlab.xfce.org/xfce/xfwm4/-/blob/xfce-4.14/NEWS#L7-44
