Created attachment 124737 [details] screenshot 1 I'm on Arch Linux x86_64, LO 5.1.2-1 and GTK 3.20.3 as title explain and the attachments show, there is a problem with LO dialogue boxes, print and save as well as all windows "born" from LO, e.g. options, customize, sort, etc.

-screenshot 1 shows the problem on the print dialogue -screenshot 2 shows simply that the icon, although with graphics problem, works in fact I can click it NB: if I disable LO dialogue box from tools->options->LO->general, LO will use 'standard' GTK print dialogue and the problem disappears
Are you sure this is a LibreOffice problem? Apparently you’ve installed some GNOME Shell extension that is doing that…
it is true! I disable `Show application menu` via gnome-tweak-tool anyway: 1- other apps fully work without problems 2- even disabled, there is a little problem; as you can see in the third screenshot, the application menu stops loading after 30 seconds more or less

solved with latest update of my system! I don't know if it's thanks to new GTK 3.22 or new libreoffice version... anyway it has been fixed
WFM as we don't know the fix.
