Screenshots showing the position indicator visible on the map in southern areas, showing the indicator half disappeared as i head north, and then completely gone are here: http://www.paradoxcomputers.com.au/wow/
There's also a screenshot showing the issue with the 'dressing room'/'character equip screen'. Multiple people are confirming both these issues in the comments section for WoW 5.0.x in appdb.
Suggestions regarding the open source drivers (in my case that'd be nouveau) are not appreciated for obvious reasons.
I should add also: This all occures when running the game in OpenGL mode. When running in Direct3D mode i experience a whole mess of other problems (that I don't care about because OpenGL mode is fine), but not these ones.
