Can't scroll all the way to the bottom of windows

Several windows don't allow you to scroll far enough down them to see the full list of items they contain. Observed in the Supergroup Window, LFG window, and the /search window.

I've also now found this happens in the Email window. I have my windowscale set to 1.2, if that helps.

I did some snooping and found that the window scale is exactly the cause of this issue; the larger the scale of the window, the more of the bottom of the list in the window is cut off. Likewise, if you have it set to a smaller than standard scale, affected windows will let you scroll past the bottom of the list into blank space.
