    I’ve got a very simple comp of some footage with a still picture as a masked in background.

    Whenever I use Motion Blur on this layer to give it some realistic movement I get some very odd behaviour:

    The image flickers on and off and the blur is a high speed smear although the background isn’t moving too fast.

    If I uncheck the MB on the layer all is good but as soon as I check it again the problem returns.

    Only have Add Grain effect on the layer and I’ve never seen this problem before in may years of using AE.

    Anyone had this problem/know of a solution?

    Very strange. Is your shutter angle (in your Comp settings) set really high? That would explain the smear, but not the flickering. It might be worth re-doing since it’s a simple animation just to see if the problem persists. Maybe even in a new Comp. I’d also try another image in it’s place just to see if it’s the image or a Project issue.

    Let us know, we can troubleshoot deeper.
