Strange flickering "sync" icon in editor 4.13

Hi guys,

I´ve got a very strange problem with UE 14.3. A very annoying “sync” icon (two arrows in a circle) keeps popping up in the editor (3D scene area) and flickers like mad. I´ve never had that before and I don´t know what this symbol is trying to tell me.

Background: I installed UE4 on another computer and copied the project files from the old one. Everthing works except automatic saving - I can save assets, maps and the project manually though.

Is this a bug or is something else borked?

Glad for any kind of help because this flickering icon is driving me nuts :-/ .

Bye,
Michael

Thanks, I will.

This could be nvidia Shadowplay, try disabling it in GeForce Experience.
