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

An upload of xfwm4 to focal-proposed has been rejected from the upload queue for the following reason: "This is a mircorelease update of xfwm4 that doesn't follow the policy.".
