Public bug reported:
To reproduce:
1. Enter the workspace switcher with some windows open (Super + S or click the
launcher shortcut).
2. Enter Alt+Tab.
3. Press the down arrow key or wait for the window preview(s) to appear.
Expected behavior:
The window preview comes up as usual (i.e., like when the workspace switcher is
not active).
What happens instead:
The window previews are replaced with solid black rectangles where the contents
should be.
I am reporting this from within my Precise Alpha 1 desktop, but this
exact same behavior is reproducible on my Toshiba Satellite A505-S6960
laptop's 11.10 partition, as well as the 11.10 partition on my desktop.
