Short description of error

As title. Same with every .blend and repeatable with this system config. Tracked memory usage with Afterburner, Blender requires a full restart to flush the GPU memory after attempting an animation or still image render with motion blur enabled.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Same as above--this happens with any .blend file here.

This now doesn't happen if I set all properties to default. I'll work through and find out which addon is causing the problem. Apologies guys!

You might have Persistent Data enabled in the performance panel. Some addon might be enabling it. Or it might be some other crap which happens in addon..

Anyway, if you'll find a way to reproduce the issue then we'll try our best to fix the issue! But for until you found exact circumstances needed to see the issue i'll move the report to archive. It's easy to re-open it anyway :)
