Okay I got it. I have a Dual Monitor Setup. Mon 1 was my X-Plane Monitor and Mon 2 my EFB Monitor. Mon 2 was also my main monitor! So when when you use X-Plane on your secondary monitor you'll get this "menu issue". This Setting also have some kind of window position issues because I noticed that all X-Plane popup windows (like the IOS) opens in the right corner and you have to move them out everytime you reload X-Plane. The reason I used this switched setup was: When I used it the other way round an annoying flicker blinking occurs everytime I klicked "outside" the X-Plane window. I solved this now by adding one pixel to my vertical resolution (1921x1080).
Hi Jan,
I think I messed up my X-Plane installation. When I change to windowed mode x-plane switches to my second monitor and stays in fullscreen mode
But yes, I don't have the problem on the second screen.
Yes and no. I Use two Monitors one for X-Plane and the other for "EFB-Tools". X-Plane runs in Fullscreen-mode. The Gizmo Menu on the right side is also missing.
