I'm getting blank icons for stacks (e.g. Downloads) and grids (e.g. Documents) in the Dock. Nothing seems to fix it. Have tried relaunching the Finder and even a full reboot, but nothing helps. Any ideas?

I'm running Mavericks (10.9.2). Problem started recently, but I can't tie it definitely to the 10.9.2 update.
UPDATE: tried restarting the Dock and that got back 2 or 3 icons, nothing more.
Here's an example of the problem:
