Having the same issue. Seems like some of the windows are clickable only sometimes. And hovering over items/buttons in inventory is blinking. I can provide video if needed. Please look at this issue, game is great but almost unplayable at this state. It looks like bottom conversation window works fine. But inventory window and combat log window are definitely bugged.
