I can confirm that this bug is not limited to computers with Nvidia graphic cards. This computer only has Intel integrated graphics (Sandy Bridge Celeron G550/ Intel HD Graphics).
I kept "Show live previews of windows in the Switcher" disabled (see my comments #12 and #13) and since then never encountered this bug again.
