<p dir="auto">I use an external monitor with my MacbookPro (OSX 10.9.4 Mavericks). I use this monitor as an extension of my desktop on the laptop. During the day I make Atom fill the entire screen (I snap the window, a feature I have enabled using BetterTouchTool). When I disconnect the external monitor and attempt to use Atom on the laptop's screen it is too large, as if extending off the screen. To find it again I have to click into Atom, go to the top bar, Window -&gt; Zoom. Once I do this it properly fills (again, not fullscreen) the laptop's screen.</p>
<p dir="auto">At first you might dismiss this as saying the 3rd party app (BetterTouchTool) is responsible. However, Atom is the only application that this happens to. I also keep Chrome and Outlook in the same - window filled via snap mode on the fullscreen. Both of these apps will extend too far, but the height will be correct and I can again "grab" the window by the window title bar.</p>
<p dir="auto">Thus I am led to believe there is something going on with the window settings for Atom, but I don't know enough about this topic to dig any farther. I was able to replicate the issue on a co-workers Mac, but we have similar environments so I can't promise that this isn't being caused by something else.</p>

Resizing Chrome: easy because the title bar is showing - I just snap it to the top and it fills the screen<br>
