I'm a new to carbonite, so I'd like to ask, if this very colorful and nearly solid (intransparent) quest areas are intended or perhaps a graphical problem.
See the screenshot of Westfall:
I have a Radeon 5850
WoW in windowed mode
Many other add-ons activated:
Cartographer
Gatherer
...
I did deactivate Cart 3.0, QuestHelper and TomTom.
