If it's showing up blank...not sure what that would mean. Anyone?
In not that...(Dusting off Mac support guy cap...)
Have you tried...
- logging out and back in
- restarting the machine
- changing the screen resolution (does this change where the rectangle appear)
- creating a new user account and seeing if it happens there
- connecting the monitor to a different Mac, if possible
?
The little white rectangle is a leftover from a tooltip that is not "cleaned up" properly. I solved the problem by simply disabling tooltips in Firefox.
Hoping to help,
