Editor: Game Scene not updating (camera, on off)

Hi there,
I have updated to 5.6.0f3, and am starting a new project. I am adjusting items, moving dedicated cameras, turning them off.

My issue is that, my game scene is not updating in real time, if at all.

Anyone seen this before?

i’ve got that (2017.3.0p3), and event made a screen to force updating of game view…
finally, i’ve seen somewhere that reset layout to default was a solution, and it seems to be.
