Sounds like something from the Accessibility preference pane is active. I've heard about it. I guess you've accidentally activated it through its keyboard shortcut. Don't remember which it is... :/

Ah, yes. Cmd-F5, I guess...

Black Square:
01. Locate and select 'System Preferences'* 'Universal Access' Utility.
02. In the 'Zoom' panel click on the 'Options...' button. A drop down sheet will appear.
03. Locate and click on the 'Show preview rectangle when zoomed out.' check box, to remove the check mark; and, then click on the 'Done' Button.
04. Quit 'System Preferences'.

* - 'System Preferences' can be accessed via the 'Apple, System Preferences...' menu item, the 'System Preferences' 'Dock' icon (if not already removed), or - from within the '/Applications/' folder.

Extra Menu items:
The non Apple provided menu items ...

(notice the missing '...'s, which means the action will take effect immediately) ... may be the result of a third party utility. Do you have 'FruitMenu' installed? if so, it is only through its interface that the above, or some of Apple's, menu items can be removed.
