Consistent stutter as soon as taxi starts

[Nealius]

As soon as I start taxiing I get a consistent stutter, particularly noticeable in VR. Oddly, when this stutter occurs the navigation panel's WP/AD switch gets reset to AD after I had set it to WP during startup.

Track too large for direct upload, so adding to Google Drive: here
