I have a similar issue, and it does happen all the time Several applications running maximized (normal size works fine): e.g. firefox & terminal.
When I alt-tab from one to the other the new window looses input i.e. no keyboard focus, the window contents are not click-able. The menu items do work, but don't show response in the window. I'm looking at an image of the window not the actual application. For if I un-maximize or 'F11' the window the focus is back. Same happen if I click the application in the launcher bar, but again only in maximized mode. Assuming it's a display issue, this is the fglrxinfo output: display: :0 screen: 0 OpenGL vendor string: ATI Technologies Inc.
