When you invoke redraw-display, Emacs on X calls the function x_clear_frame, which calls x_clear_window, which calls XClearWindow. Do you see this sequence of calls if you step through the code with a derbugger? One possible reason for not clearing the frame is that you have double-buffering enabled. Can you disable it and try again? (If you don't know how, search for "double buffering" in etc/NEWS.26.) Failing that, the only way I can explain this is that you have some "optimization" feature in your video hardware and/or driver, and that is the cause of all the problems you report in this thread. Please review the settings of your video driver software, and turn off any "optimization" or "advanced" feature you find there. If that doesn't help, maybe upgrading to a newer version of the video driver will help.
