menu displays - where words should be

On Fedora Linux, using Version: Build ID: of LibreOffice and the menus only show a - where the menu words should be. If I grab the border and drag it a little then the words show up but only until I click a menu item, then they go away again (so some type of painting issue it appears but how can I debug the problem). Hard to use the submenus like this since I can’t the submenu words to know what I’m doing. Advice is greatly appreciated. Thanks.
