I've encountered this when I tried Retro Mode (it rocks!) with 1600X1200 resolution, on MacOS 10.11
So, when:
1. I set a resolution with a ratio other than my monitor's 16:10 eg. 1600X1200 for Retro Mode
2. and I set Fullscreen on
3. and regardless of the "Free Scaling" setting in GUI
The game behaves as if the UI elements (buttons, inventory slots, travel map search field, everything) are stretched.
I've included a screenshot of the in-game travel map to better illustrate what I'm trying to say here.
If I turn off "Fullscreen", the UI behaves.
I hope this helps. If you think I can provide more info, just let me know.
Cheers!
