Thin line at the left of Simple Scan's "Scan" headerbar button

Status changed to 'Confirmed' because the bug affects multiple users.

I'm guessing/hoping this is caused by the use of a dropdown-menu in the button. So not very common.

I fixed something similar recently, I'd like to work on this, too

With Marco's recent changes to the theme, it's looking actually worse (see the attachement on the duplicated bug: https://launchpadlibrarian.net/341149727/Bildschirmfoto-20171017100606-674x515.png). c-lobrano, any progress on your fix?

The left glitch is allready visible in the screenshot in this bug. But the glitch on the right side of the button could is not. It could be a product of my german system language which expanded the button tue to the german word "Scannen" which is longer than "Scan"

Hi Didier,

yes, I notified Marco about that and I needed to rework the initial fix, but a first proposal should be ready today or tomorrow at the most.
