Using the -popupwindow I was able to start in borderless window mode, which is actually quite nice; however it did not fix the problem. Also when the problem started I was using full screen the whole time; I only tried windowed mode to see if that would fix the problem, sadly it did not. I also tried various other screen resolutions and even the Disable desktop composition option which has worked on other games in the past, but sadly nothing seems to be working for me. So I'm still missing the altimeter, also I noticed when I switch back and forth to map view using the M key the altimeter does transition off screen with a sliding effect just like the other UI components (pilots, and staging info), So is there maybe there's a key combo to hide/show the altimeter in map view?
