Strange behaviour during rendering

Imago

Until now, when rendering in 3DLight, the timelime moved frame by frame and the viewport showed the frame that was going to be rendered.

Now, the timeline moves forward but the viewport doesn't change, it shows always the same frame. It behaves like if  I'm rendering in Basic mode.

The output images and videos have no problems, they look exactly how I expect.

I tried updating the video drivers and changed every graphical option, it still shows always the same frame during rendering.

Anyone else is experiencing this?

Don't render in 3DL, but in iray my viewport gets stuck while rendering, it doesn't show the scene at all, but copies whatever goes in front of it, like if I open the browser etc. It seems to only happen on win7 though, my short trail on win10 didn't have the viewport bug.

Ah, yes, that happens to me too some times. If I open a folder or another window the viewport becomes totally white.
