The LibreOffice 5.4 in the daily build came with it. Unlike you, I didn't install it from deb.
The bug has nothing to do with a VM or not. All themes with a dark header bar do this, unless they are fixed. Like I said, look at what Adapta or United did to correct this. Or you take it to LibreOffice to correct this. But it will be faster to fix the theme. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1704745 Title: Ambiance light-themes - LibreOffice has a white square top right To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-themes/+bug/1704745/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
