This affects gtk3 indicator in Xubuntu (xfwm or mutter as wm). Usually the black borders in the attached screenshot are transparent shadows, but it represents exactly the area which is sometimes not clickable.
To reproduce: * click a gtk3 indicator * hover over the expanded indicator menu * try to click the indicator or any neighbors => only clicks in the upper ~1/3 of the button show a reaction, the lower 2/3 do nothing. The same thing happens with some gtk3 window shadows, e.g. the gnome calculator: Underlying windows cannot be brought into focus near the window border in the shadow area. ** Attachment added: "black_border_indicator_plugin_no_compositing.jpg" https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1521586/+attachment/4618533/+files/black_border_indicator_plugin_no_compositing.jpg -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1521586 Title: Frame shadow of gtk3 application is not transparent for mouse clicks Status in gtk+3.0 package in Ubuntu: New Bug description: The shadow region of Gtk3 apps drawing their own frame shadow (CSD) is not transparent for mouse events. E.g. when such an app is in front of a browser window, a link in the browser can only be clicked/hovered at distance from the window border, which is larger than the shadow thickness.
