Big transparent red circle in my lower vision. new or something wrong?

[silent_one]

Ive been away.  So i dont now why Im now getting a large transparent red disc in my lower vision.  Its about 5cm across  moves anywhere my vision moves.  Looks like a radar hud but doesnt seem to do anything. Its also there in the initial game load screen.  When Im looking at aircraft at game start it onscreen then too. 

I cant tell is this is part of something new and I dont now how to turn it off. Or is it a bug or an artifact of my new n videa drivers.

Any help much appreciated.
