Shadows appear/disappear in a line?

[Bog9y]

Using a Reverb G1 VR headset, terrain object shadows to default. 

 

So with 2.7 I noticed that the shadows of objects (like trees) seem to appear/disappear in a line as you fly over them.  It's hard to explain exactly what I am seeing but as you fly along it's very noticeable that object shadows seem to disappear as they pass below the aircraft/a Field of view. It's as if the shadows disappear when the object is about 0.1 nm from the aircraft and creates this weird effect as if something is moving in the corner of your eye. 

 

Did anybody else notice this? Is there a setting I should change to fix this?

Can confirm in 2D as well. I noticed the same while in external view doing screenshots.
