Photoshop 13.0.5 window dragging issue (OS X)

Hello everyone! I'm having one small issue abou this: when I drag an open document window partially off the screen, somehow like this:

then release it, and then drag back, the sides that have been hidden (outside the screen) won't redraw until I release mouse button:

Haven't noticed such behavior until 13.0.5 (upgraded directly from 13.0.1).
Thanks.
