Ambiance light-themes - LibreOffice has a white square top right

By the way, I think that a mix of Pop!_OS GTK theme (from Adapta) and United-Gnome Ubuntu shell theme would do a great job. See attachements for an example. The United-Gnome GTK theme would be nice too.

Confirmed on Ubuntu 17.04 using Libreoffice 1:5.3.1-0ubuntu2

I cannot reproduce the issue anymore with LibreOffice 5.4

I do see the issue in 17.10 still. But to me it looks like a feature, if not a bug. The "white square" ties the close button to the document area. So it looks intentional and logical. Maybe it's not intentional, but either way not a big problem.

It's not a feature, it's a bug in some themes. If it was a feature, the "white square" would somehow appear in themes like Adwaita. But it doesn't. It would also appear in MacOS or Windows. It doesn't. Please, get real. ;-)

By the way, in Ubuntu 17.10 daily build, and LibreOffice 5.0.4, the bug still exists. See attachement.

Yes confirmed the bug is still in 17.10.

That's weird. Do you think that the VM might affect this behavior? I just installed latest 17.10 build and Libreoffice 5.4 from debs in Virtualbox and the issue seems gone

Yes graphics driver could be a factor. Also your screenshot suggests maybe you're not using Gnome Shell, maybe Unity?...

It's Gnome Shell, with Activities, new Ubuntu Dock bar and everything.

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.

Sorry, I don't understand why installing it from .deb should change the behavior

Adapta seems affected as well to me, it's just less noticeable. If you look at the picture the headerbar's border stops just below the close button on top corner.

> Sorry, I don't understand why installing it from .deb should change the behavior

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"
