Post Process Flickering ON\OFF during IRAY

[Stenchfury]

When rendering with Iray and trying to save a picture from the camera menu; everytime i click the render window or anything within it the post process effect seems to disable for a few seconds; on lower iterations that is beareable but on higher iterations (500\more) the "flickering" last many seconds or even a minute making "taking screenshot" of the render very frustrating; if I click and try to save it it saves without the post process ON, so i have to click; wait until the render window refreshes hovering over the menu, and then save. this might take various minutes for only taking a snapshot, and making almost impossible to make post process adjustments when the render is done (pausing the render doesn't help, the flickering still occurs).
This seem to happen even with the sample material provided.

Is there anything causing this and how can it be prevented?

Whats are the specs of the pc your using and how many drawcalls are you creating with your painjob via materials displayed?

Intel i7-5930K 3.50GHz, 32GB DDR4 RAM; Nvidia Geforce GTX970;

The Material is a simple PBR Diff+Metal+Rough+Normals+Emissive; it's an already texturized model used to test out the render; and as said I tested it out also with the sample material provided with the software and it gives the same problem.

Any Clue? This thing is driving me crazy; can't have a stable render here; everything keeps going on and Off
