If a window is scrolled so that a partial line is visible at the top of the screen, then the numbers for the window selection are also only partially visible:

Shouldn't the numbers be attached to the first fully visible line? This situation happens all the time when you are scrolling using a command like mac-mwheel-scroll that scrolls by pixels (assuming that mac-mouse-wheel-smooth-scroll is t).

One possible fix might be to do

(set-window-start window (window-start))

inside your aw-offset function, which has the effect of shifting the window down by a fraction of a line so that the whole top line is visible. It ought to be a no-op if pixel scrolling is not in use, but I haven't tested this.

I am using the Emacs Mac port from Homebrew:

I think this is only possible to do on OSX. I have only GNU/Linux available, so I can't debug this issue. If you know of a way to enable partial scroll on GNU/Linux, let me know. Otherwise, hopefully there will be a patch from an OSX user to fix this eventually.

Maybe this package works better in your case.

I believe pull request #78 should fix this as well. Can you give it a try?
