wpreviews needs a fix for occasional incorrect xprop output

[Jacob Vlijm]

[EDIT] Master SRU fix covered by (LP: #1771606)

Budgie Extras is a set of python based applets that are either preinstalled or are available to be individually installed. They are exclusive only to budgie desktop users and cannot be installed or run on any other desktop environment.

A number of issues have been raised since the 18.04 release. As part of ongoing 18.04 support the Ubuntu Budgie Team proposes to wrap up fixes on a very targeted basis. In this series of SRU's we have wrapped up DR's that have been classified as LOW by the UB dev team. In addition the scope of the change has been assessed to limit the potential of regression. This is to ensure each SRU request is strictly limited in scope with the risk(s) being easily determinable.

[Impact]

 The Windows Previews applet occasionally fails to display any previews of windows. Worse, when this happens the user has to reboot or logout/login for previews to work again.

 The impact is for Ubuntu Budgie only and anyone running the budgie desktop together with the QuickNote applet.

[Test Case]

 1. Using Budgie Settings, check that on a panel the Windows Previews applet has been added - please note, the windows previews applet is installed through the package "budgie-previews-applet"
 2. Open several windows as part of your daily usage. Use windows previews to switch windows.

[Regression Potential]

 * None.

 * Ubuntu Team has worked with the originator of the issue (see discourse link below) and verified that the fix works.

[Other Info]

 None

EDIT:

Original description

xprop is used to fetch window properties. occasionally incorrect output breaks the background process. The issue is described here: https://discourse.ubuntubudgie.org/t/alt-tab-buggy-at-random-times/631
