When I use a sokokar at a post, I get a Selection window that pops up on the left side with things like "description that is too long" or the like.
This is fixed along with the lack of all your destination choices.
Icons for stop and recipes not showing up on tradeskill window
Fixed; new UIBuilder keeps breaking icons 
The 'message window', the one where if get a quest update, or enter a new area, is entirely transparent - I don't see any message, though I sometimes will happen to have my mouse over the area it appears and get the 'move window' icon for a few seconds.
I've had this issue too, happens when I have unknowingly resized the onscreen message window. You have to be quick to right click it to get window settings to fix it.
