There are some problems with the chat/combat log in regards to the mouse scroll wheel.
If the window is locked ('allow clicking through log window'), mousing over the window and using the mouse scroll wheel seems to BOTH zoom the camera and scroll the through the text. However if it is unlocked it seems to work normally.
However, there seem to be an additional problem, which is if you toggle 'allow clicking through log window' and you do not remove the mouse pointer from the window and then scroll with the mouse wheel it will zoom the camera and not scroll the text.

Also during character creation when I was customizing I noticed that if I hold the rotate right or left buttons and the character rotates past a certain point it just flips around (a quick awkward and likely unintended spin) for some reason rather than continuing the smooth rotation that it should have, then it will continue to spin normally. Though with that being said I've had trouble consistently reproducing it, it seems rare and minor as far as issues go.
