3.001: A20 disappear and then pop up again (MP and SP) - that's buggy

[ShredderSim]

A20 that were clearly visible at the clear blue sky suddenly disappear at distances between 2 - 5 km and then suddenly pop up again. All other planes and even smaller fighters at the same distance near the A20 stay visible w/o that strange "magic hood" behavior.

 

Sometimes this effect occurs even when I zoom in = they disappear and when I zoom out again they appear again. 

 

This occurred in several maps in MP and SP carrer and short missions.

 

My IL2 graphic settings are 2560x1440, Ultra, 4x quality, distance 70km, SSAO and HDR on, 4K skins, Anisotropic filtering="sharp", AA = 2

I am being told this does not happen with PE2 etc so I wonder if it is related to the 4K skin?
