Rapid clicking causing UI window to shift up & to the left

If I'm at a vendor, and I want to buy something, if I click repeatedly to increase the amount I want to purchase, the vendor interface window suddenly shifts up and to the left.

Same thing in a crafting window. If I'm adding fuel from my inventory, if I click repeatedly quickly to add more of an item, the fuel window starts shifting up and to the left.

I've asked guildies, and they say they're seeing the same thing.

Seems to have been fixed this week.
