So, love Carbonite, been using it since Wrath. However, the minimap screen has developed a bug where a permanent copy of a previous image from the minimap is overlayed on top of the minimap. I have attached an image of an enlarged minimap so you can better see the issue. The overlay is in the top left corner, and it does not change size, so when you resize the minimap the image just sits on top of whatever the minimap is displaying. Also, closing and re-opening the minimap doesn't make it go away.
Edit: I attached a second image to show how annoying the overlay can be. I am currently flying over Stormheim in Broken Isles. The overlay is showing the Dock in the Zandalari Capital.
