hopefully you can see all screenshots from that link.
The problem i have is only in certain places, i get huge black circle on map i tried changing mini map setting and transparency but cant seem to figure it out, to zoom out makes the black circle smaller but then i cant see much else as zoomed out to far started happening last night i changed nothing and was working fine the day before
it's minimap transprancy settings, some spots don't allow the map to be transparent or it goes black like that. Sadly it's a bug with WoW not with carbonite so I can't fix it.
Enabling the "Bugged Zones" options will try to fix some by disabling the transparency if it knows it'll happen, tho not silvermoon since no one ever reported that one as a bugged zone before.
