I have a theory that the problem could be the fade plugin failing to post damage for the faded window, but still redrawing it. So unity never gets told that it needs to redraw the switcher/overlay on top.
Please try this and tell us if it hides the problem:
CCSM > OpenGL >
framebuffer_object = OFF
vertex_buffer_object = OFF
always_swap_buffers = OFF
