I recently attempted to upgrade my Nvidia graphics driver but that didn't go well. So I uninstalled the new driver and reinstalled an older one.
Now I've got my desktop back and all the graphics are just fine, except for one caveat.
When I move my cursor down toward the bottom edge of the screen, the desktop "scrolls" to reveal an empty space below the bottom panel (see the blue space in the screenshot).
Moving the cursor to the top edge of the screen scrolls the desktop back to the way it was.
It seems like a nifty feature for those who want it, but I do not.
Any ideas on how to disable this scrolling effect?
