Created attachment 126673 [details] Screenshot of dialogue in calc Fresh installed Ubuntu 16.04 included Libre office 5. In the dialogue windows however many (not all) headings in bold character display as black variable squares, unreadable, making the use of it difficult or rather impossible. Using the check-/text-/or scroll-box under the heading can/may change a readable heading to unreadable. For me, this is serious and makes the use of Libre office rather impossible.
