[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
