That's a different issue from the one we're discussing here and I believe what you describe is the issue mentioned in the NGX documentation.

You are discussing a bouncing issue in P3D v.2.5; I'm using a plane, any plane, be it Just Flight, be it PMDG in P3D v2.5. and the bouncing occurs in P3D v2.5. so how on earth can it be any different?

Different in the way it's different kind of "bouncing" and different causes.

 

If you go back in this thread it will be clear I think. The issue I reported when I started this thread now seems to be related to the scenery.

Problem solved thanks to Victor Buchkov, you can read the details here.
