The first two glitches are visible in this screenshot:

#1: The group is in scouting mode and I hid the middle UI console, now the green indicator is on Durances portrait.

#2: My main character doesn't have three weapon sets, only two, but three are visible. The third one is Kana's, but it's still visible for other characters after switching Kana's weapons sets.

#3: It's fairly impossible to drag and drop items from one character to another when in the shopping menu, the character list scrolls in a way that makes the item transfer impossible. Try it. Single clicking the item adds it to the sale, so you have to drag and drop.

#4: Often mouseover information doesn't appear on items you're looting. I'll take a screenshot when it happens the next time.

#5: Not 100% sure about this one, going to test it after posting. If you loot an item by dragging and dropping it on a character portrait, the number of empty slots that character has doesn't update.

 

There was a sixth UI glitch, but I couldn't reproduce it. In the custom formation menu I dragged Aloth's portrait on my main character's portrait and Aloth's portrait graphic was multiplied, so there were two Aloths in the formation.

Didn't think creating a new thread was necessary for this, but it's UI related:

 

The yellow lab pet dog you can buy from the tavern in the Copper District of Defiance bay has its own health bar in combat, even though it's just a pet.
