its common after installing a new livery/scenery of even the latest update for it to take a while to load. find it to be the case the first time i load a flight. it loads faster there after.
same thing in msfs2020. I found that i just press CTRL once then type. Press it again to end "keyboard input active"
this is what happens when just pressing the ctrl button and not releasing:

MSFS2020 with the latest update for this scenery. Attempted to uninstall and reinstall with no changes. Image is an example of what is seen all throughout the airport. Thanks!
