UPDATED: I found that this happenes whenever I run the sudo -i nautilus command.
The Unity bar is changing colour without my request. I am not changing the background (I know it automatically adjusts to your wallpaper).
It is normally set to a dark orange which it gets from my wallpaper. But sometimes, it bugs out and switches to the default purple. This also messes up my conky configuration and creates a red background around the conky window (which is set to dock mode).
I was messing around and installed Gnome over top of Unity... and I've recently removed Gnome (not all of it though, login screen is still there for some reason) and I am wondering if the Gnome desktop change might have messed something up...
Here you'll see the way it should look.
Here is what happens.
Note that the conky goes red, and the Unity bar goes purple... What can I do to troubleshoot this?
