Flickering clouds issue solved in 2D but remains in VR

So I was one of those affected by the flickering clouds issue after update # 5 which affect some gfx cards. I am using a GTX780 GB VRAM (STRIX ASUS) and Rift CV1

Now, at version 1.12.13.0 that is solved in 2D flying but with VR, the issue still remains:

Clouds are flickering and the layer/ frame/ window (whatever to call it) on which the clouds are projected stick with my head movement.  I can only fly in VR with Clear Skies. 

I know my CPU is 10years old (i7 980X) and Gfx card 5 yrs old but still .....VR is working above expectations. I had expected a slide show but it is performing very smooth with my old rig.  

Anyone having the same issue with the clouds in VR ?
