There's scaling problems when the resolution goes more square than 16:9.
Basically it only snaps the UI to top and bottom, so if you`re playing on a 16:10 screen, UI elements will be out of the screen. It gets worse as you go less wide.

The OK button on the character creator snaps to the bottom left corner of the screen, the rest of the UI doesn't.
I have about 40% of the left column of race buttons and on the right side my text cuts out the Bonus button and shows "Bonus sta".
After creating the character the game looks right.
In the dungeon I have my left character portrait covered by the 5 slots on the left.
So floating UI buttons are correctly snapping to the corners of the screen, but the screen itself still doesn't zoom correctly for taller displays.
