Text in various in game windows doesn't consistently display.

For instance in this Screenshot, the System Window (center of the screen), the Quest Tracker, Button labels, Mouseover popups, HP/MP/TP bar labels etc...


Sometimes changing view angle, or waiting a LONG time (minute plus) and the window text will draw.

I have tried turning on and off various graphics settings, default settings from Max to low, Windowed, fullscreen...
