Yes, it's GTK3 - see below #3.

On My Kubuntu VM (repeated to make sure):

1. With gb.qt5 / Breeze, 'Border=False': Background and Border are not rendered during development- and run-time, but the Border is rendered when hovering above the button.

2. With gb.qt5 / Breeze, 'Border=True': Background and Border are rendered during development-time and run-time.

3. With gb.gtk3/ Breeze, 'Border=False': Causes the background to disappear during development-time, but it appears during run-time (see screenshot).

4. With gb.gtk3/ Breeze, 'Border=True': The background is displayed in development-time and run-time but the border is only displayed in development-time.

With this result the appearance of a Button is some kind of lottery. 

Particularly above 1, 3 and 4 raised some concerns with regard to a possible bug because of the differences between development-time and run-time.

Best regards
