I have two screens, using TwinView.
A larger one on the right (my primary screen), and a little smaller one on the left, which is also postioned a little bit lower than the big one.
When I switch windows using ALT+TAB, and the active application is on my secondary screen, the window switching stuff (I don't know how you actually call it) is shown on that very screen; but it looks a little bit screwed up. It's best described with an screenshot.
As you can see, the area of the left screen that is beneath the right screen shows a part of the window, which it should not do.
Steps to Reproduce:
1. Use 2 monitors, one of then positioned lower than the other
2. activate a window on the lower screen
the window switching indicator (or however you call it) looks messed up
it should *not* look messed up :-)

note that the left monitor is actually a little bit below the right one.
same problem as bug #184874 - just different direction
