I noticed it most buy running
I've found a bug whereby sometimes, in full screen mode, the dock doesn't hide and you get an odd reflection. (The Icons are gone, but the bar is still there.)
git diff | sublbut it can be reproduced with
echo "hello" | subl
I have highlighted the issue with a skitch screen shot (the original is here), you can see at the bottom of the page the text has gone "funny".
