I can not reproduce that using your test program. I have seen a similar problem on rare occasion, though: Window contents, especially of larger windows, were stuck at that time and could be recovered only by unmapping and re-mapping (minimize, shade) them. Unfortunately I didn't find a good reproduction scenario so far, and I really don't know what should cause that. Are you using Nvidia's drivers, by any chance? Another shot in the dark: You can try playing around with the "Force synchronization between X and GLX" option in the workarounds plugin. Perhaps it's just the sort-of-well-known redraw issue caused by race conditions in the X damage protocol. > 2) When a window has fullscreened and used > _NET_WM_FULLSCREEN_MONITORS, if > any tooltips are used in that window (as this simple > application does), > Compiz will cause the screen to flash repeatedly until the > user stops > hovering over the originating widget and the tooltip goes > away.

You want to disable "Unredirect fullscreen windows" (in ccsm it's under General options). Ubuntu enables it by default (both settings have problems: enabling it causes the problem you're seeing, disabling it causes speed loss in fullscreen OpenGL apps, e.g. games).
