Created attachment 364624 Showing menu gap in gnome-terminal when above 2nd monitor top

I have a dual monitor setup using my laptop. The external HDMI one is setup at 1920x1080, and the internal at 1360x768, and virtually positioned on the right bottom to the other. I do this in order to be able to have a consistent display (the laptop monitor is small).

When using an application like gnome-terminal (and others). If the window is located in the upper part of the big screen, if I click on a menu, it displays the menu content with a gap, putting it at he level of the top of the other monitor.

I attach some images.
