Bug 707581

Description of problem:
I'm running a rather non-standard setup by having two displays not next to each other horizontally, but vertically: one display is above the other. The upper screen is 1280x1024, the lower is 1024x768, and the smaller one is aligned to the right edge of the larger one. I have a desktop spanning over both display, and the upper display is the primary one.

This means the notification "panel" is at the bottom of the upper display, and there are these problems in this setup:

1) When the panel "hides" when the mouse is not over it, it actually hides into the lower display area. There are no icons on it, but there is a shaded stripe. This stripe also makes anything under it insensitive to clicking (it's impossible to e.g. close a window if the closing 'X' is under this stripe. Screenshot 1 shows the location of the stripe.

2) When a larger notification pops up, it does that in the middle of the screen, divided between the two displays, which is ugly. Screenshot 2 shows the division of the notification


Version-Release number of selected component (if applicable):
gnome-shell-3.0.1-4.fc15.x86_64

How reproducible:
always

Steps to Reproduce:
1. set two display desktop, one display above the other
2. set the upper display as primary 

  
Actual results:
See the notification panel "hidden" in the lower display
See the notification show split between the displays

Expected results:
Panel does not "hide" in lower display, and does not overlay & disable elements at the top of the lower display
Notifications show in the upper display entirely.

Additional info:
I would be happier to have the notification panel at the bottom of the lower display, but that's another story.
