If you play at 21:9 aspect, 3440x1440, when trading with npc, the top and bottom of the trade window get cut off. So you can't see how much coin you have, or how much the vendor has. This also affects just viewing your own inventory. The bottom item gets cut off, and the top heading part gets cut off. Not too big of a deal in inventory, but when trading with NPC's its important. No idea how much coin my char has until I run out spending it.
A simple zoom out a small bit on the UI would fix it. or allow the UI to be affected by the FOV, and a higher fov would help or fix it.
One other thing I ran into, when in the character creation screen, clicking the words for Body, Face etc did nothing. I had to click above them to get it to register the clicks. So a second UI issue with 3440x1440. The positions for clickable parts of the UI are not scaling with this resolution.
Loving the game otherwise.
