The following issue could be observed on 3 different PCs, two with Solus Budgie and one with Solus MATE (Of course all DE's with active desktops):

It is not possible for me to create an executable desktop-shortcut of any LibreOffice program. After dragging and dropping it from the Budgie/Brisk menu to the desktop it shows no graphical icon (which is similar to other desktop-icons which seems to get their icon after first time launching it). I can not launch LibreOffice through the shortcut it gives me an error "starter for no trustworthy applications" which i can only abort. The created shortcut displays an arrow overay (meaning it is a shortcut) and a lock. All other tested shortcuts ask for permission after first launch and get their correct icon.

Also i cannot change the owner of the LibreOffice shortcuts via GUI as it's owner is root. With help of Marius from Ubuntufun.de i edited the shortcut with nano to make it executable for me.

But i think that is not the wanted behavior as LibreOffice seems to be the only application which owner is root and which creates no executable shortcuts.
