I'd llike to add that it is only on desktop 0,0 and none of the others. I don't know if it is some Gnome desktop or e17??
Anyway it sucks and I either want it removed or adjusted to fit.

What has been tried:
I created a modeline and added it to the xorg.conf monitor sectoin. The only option under my screen area of that file is "1920x1080"
When I use the terminal and type xdpyinfo I get that the screen resolution is 1688X964. I assure you that neither of those two values appear anywhere in my xorg.conf file.

Long story short: What is it? How do I fix it? How do I make it go away?
