After opening the "Edit Profile" window in the launcher, all of the ui elements get redrawn strangely (my guess is that they draw relative to the mouse). This is most noticeable in the Edit Profile window, but also applies to the main launcher window after having opened the Edit Profile window. I don't know when this started, nor how to recreate it.

Update: this only seems to happen the first time the launcher is open. Restarting the launcher will allow the ui elements to render properly.
