I'm not sure if this has been reported already, this is the main reason why I don't have the map 100% scale.
I currently use the map lower sized, but I have to have it in certain position so it doesn't happen what you can notice in the footer. I've been looking for an option to fix it but I can't seem to find it... is it possible? I'm using one of the latest versions from files.wowace.com.
By the way, those action buttons are the ones built-in the game, I don't use any addon that gives that funcionality (at least for now).
