Aside from the bug report, as a short term fix... As part of that resetting thing, have you tried completely clearing out your character's local files (ie at the filesystem level)*? You'll lose your HUD setup, hotbars, basically everything, but it would be interesting to see if that fixes the map.

*Rather than deleting, I'd suggest moving the files elsewhere so you can restore them if it doesn't work.

Either way, good luck with this.
