Comment 5 for bug 261716

I don't really notice this when switching between workspaces.

However, other compiz features, such as "Group and Tab Windows" cause the blanking of the window list to be permanent until something forces a reload of the list (such as a new window):

1) Select two windows (super+s default)
2) Group them (super+g)
3) Make a tab group (super+t)
4) Change tabs (super+right_arrow or super+left_arrow)

I have an Nvidia 9800gtx+ with Nvidia 177.82 drivers installed.
It only happens when the gnome panel "expand" preference is disabled.
