When closing atom when it's resized to fullscreen, then restarting atom doesn't result in a window.
Use the following steps to reproduce:
- Install atom from the deb (https://atom.io)
- Set Atom to fullscreen
- Close Atom
- Restart Atom. It starts but there is no window...
To get the window back use super + up
(restore window size).
See the following gif, on a fresh virtualbox installation with a fresh atom install.
