Short description of error

When I change the active Camera the image has really much motion blur (when motion blur is activated) even if nothing is moving

Exact steps for others to reproduce the error

Render image, choose other camera, make it the active camera, render with it

Can confirm this in current master (worked in 2.79b)

made a stripped down version (less renderlayers, less samples, no denoising, 25% resolution, only 2 cameras...)

Note that Persistent Images option seems to be the cause, disabling that fixes it for me...
Will have a look if I can hunt that down...
