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.
