Thanks for the quick response!
@ spiel2001: When I used that command and it released the map to the top of the screen, I no longer have any problems with the map blurring to the side. Before patch 3.1 when I was running the release version of nUI rather than the developer I didn't have the problem, which was why I thought it was related to nUI.
@ Dramber: I'm 100% sure it's not related to that sort of lag. I have a $6000 system and I've never experienced any lag in any program before; I also never had the problem until switching to the developer version of nUI, so it sort of made sense that it was related to nUI.
It only happens in cities, if that helps at all? While I do love having the map docked neatly beside my character image, I'll leave it out of nUI's control if it works that way.
The only unfortunate part is that with that command, the circle that usually holds the minimap has the map bleeding outside of it as a square rather than a circle. :?
Thanks!
