Description Andreas Kloeckner 2011-04-25 14:46:05 UTC 
My driver (i915) on its namesake chip (i915) does not support GL acceleration if the aggregate virtual screen size is wider than 2048. This, unfortunately, is easily exceeded when using my laptop display (1024x768) and a full-HD monitor (1920x1200) side-by-side. I therefore need to keep both screens stacked vertically if I don't want to lose acceleration, but gnome shell has a few bugs in this situation.

First, it seems that the notification box is always drawn as a gradient at the top of the bottom screen, even when otherwise not shown.

Second, it does not seem that windows on the bottom screen take part in workspace switching.

Ouch :(

As far as I know, this is designed behavior. See bug 645581 for details on that.
