Ok, I finally got around to doing some screenshots of my issue.
I've circled the windows that are custom/modified in red to show the clipping, and the stock windows in orange.
I also noticed varying degrees of the issue, for example the title bar when using the musical notes on Brygards dressing room is completely cut off on the left and the top is missing on the right.
I think that it has to do with the window's defined size, but everything that I've tried to change hasn't made any difference yet.
