I got the problem that the menu that should appear when you click on an "hamburger" button in the top right corner of a toolbar doesn't appear.
This happens on a second screen when you got more than one screen/monitor, and the main screen has higher resolution than the second one. It also only happens to toolbars that are positioned near the bottom edge of the second screen and where the menu height is larger than the distance between the "hamburger" button and the bottom edge of the screen.
