Short description of error
When you are in the view animation window and pause the animation with the spacebar, whenever you move the mouse cursor the image is flickering. This even happens to a lesser extent when the window is in the background and you move the mouse cursor over the foreground window.
Exact steps for others to reproduce the error
With any animation rendered: click render -> view animation. Move mouse cursor around over the window.
