This was by the far the most frustrating issue with SU7.
Good News, this along with a bunch of other things have been fixed in the public Beta release that was released in December. While the beta is not perfect for everyone, its a great step in having a smooth flight.
Ctr + 1 didnt really work for me, so I jumped in and joined the beta, and I am glad I did.
Having a blast in VR (G2 3070 12700, oxr 100 rs 100 nis 75 sharp 50)
There are a couple of simple steps to join the Beta, then download, install and enjoy.
Hope this Helps
