When I open the menus in the GNOME Shell task bar (calendar or settings/log-out/etc menu) they are displayed but not updated when I mouse over them or click on them. I can still use them by blind clicking. When I set both screens to 100% I did not see this. I am using the Wayland session. With the internal screen at 125% I saw this too, but after changing the relative position of the two it went away. I think this was a fluke, but I was unable to do the same after going back to 150%.
