I’m sorry to report that SU12 introduced new regression which broke 3rd party appliacations toolbars scaling. Toolbars interface is now super small rendering the toolbars unusable. This was spotted by SU12 beta testers, even acknowledged as officially registered bug by @Jummivana and finally ignored by Asobo. If you VR flying experience depends of 3rd party toolbars, you can only wait for the developers to find a way around this new act of Asobo ignoring the users and beat testers. In some of the toolbars like Navigraph interface scaling options already exist.
