Created attachment 119619 [details] screenshot of delete sheet dialog in calc The delete sheet dialog has a black area in calc 5.0.3.1 under gtk 3.18.2. I have attached a screenshot. The dialog itself is still functional so this is merely a visual glitch.
5.0.3.1? Where are you finding version 5.0.3.1?
http://download.documentfoundation.org/libreoffice/src/5.0.3/ A pre-release if I understand correctly.
Confirmed. Version: 5.0.2.2 Build ID: 5.0.2.2 Arch Linux build-3 Locale: fi-FI (fi_FI.UTF-8) Gnome Shell 3.18.1 Might be a GTK bug, of course..
Is it possible that the frame is just sized too big for content and gtk+ is filling the remainder with black?
The black area seems to be fixed in Bug 93373. *** This bug has been marked as a duplicate of bug 93373 ***
