I still get some artefacts, though right now it seems to be much less then usual. How I reproduce it it to run /Emacs -Q --eval "(set-face-attribute 'default nil :font \"monaco-14\")" (it needs the bigger text it seems). I then open a file with a lot of text, like the GPL, and scroll to the bottom. When I scroll back up you can see at least one pixel on the mode line where the line numbers are that shouldn't be there. There is also some storage pixels near the are that describes where you are in the file. The more times I scroll back and forth, the easier it is to see the pixels. 

I also seem to be missing antialiasing in this version. Am I just crazy or did the text look better in 24.2?

The area above the package-list seems to be ok though. 

(I appologize to Stefan, I forgot to CC debbugs, so you get it twice.)
