Ok I found out something. The Black background in Gnome Settings and any app you see be fixed by disabling overlay scroll-bars...
To Disable Overlay Open terminal and run this command:
gsettings set com.canonical.desktop.interface scrollbar-mode normal
If you want to get back overlay Scrollbars, enter this command:
gsettings reset com.canonical.desktop.interface scrollbar-mode
This must be done on a user by user basis to disable overlay. Ideally this should not happen but it may be a bigger bug in overlay it's self it only effects certin apps. but not sure if a fix will be easy.
