Me neither. :-) But you said that you had no problem with the one from deb. Again, please take a look at the answer I got from the guy who makes the United theme and how he fixed it : "I wrote a very specific rule that hopefully only fixes this issue in LibreOffice" https://github.com/godlyranchdressing/United-GNOME/issues/135 Thanks. ** Bug watch added: github.com/godlyranchdressing/United-GNOME/issues #135 https://github.com/godlyranchdressing/United-GNOME/issues/135 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1704745 Title: Ambiance light-themes - LibreOffice has a white square top right Status in Ubuntu theme: In Progress Status in ubuntu-themes package in Ubuntu: In Progress Bug description: In LibreOffice, there's a white square that appears in the top right.
