Trying the beta at present. I notice the Approach Guides are sometimes disappearing.
This is what I observe:
1) Boxes nearer the aircraft, but in front, disappear while still a long way out. Boxes further in the distance are still visible. Boxes on or behind the aircraft are still visible, and can be seen by turning head to the side, or using the external camera. So just boxes both near and in front are gone.
2) Boxes disappear completely, often approaching a turn in the flight plan, the whole lot are gone. They usually reappear after a while.
Happens with both normal and vulcan renderer.
Could this be a bug introduced with the beta?
I'm a noob, I like the approach guides!
