Entire editor gets shifted partially off the screen occasionally
I don't know if it's a conflict with a different extension, but it occurs with my modded adwaita theme, and with the default light theme, both on Windows and Linux.
It occurs often, but not all the time, usually when opening or closing various files from the normal tree view.
I'll experiment with turning off all other addons to see if it still occurs.
The one thing that works is that sometimes, switching files with then later fix it, and also, opening up the developer tools and toggling on and off overflow: hidden on the <atom-workspace> element will also fix it, but only temporarily.
However, after fixing it with the overflow: hidden toggle, after switching back to my normal theme, it happens again.
Edit: it seems that, overflow: hidden gets re-enabled. forcing it on the element style to force overflow: visible seems to be fixing it for now 
I figured out how to reproduce it reliably: it always happens when closing a tab, where the number of tabs decreases. This bug probably has something to do with however atom or atom shell calculates the size.
I also have this same issue ...https://discuss.atom.io/t/hide-tree-package-wierd-css-error/19488/4
