Michel Dänzer 72328e5eb9 present: Only update screen pixmap from flip pixmap once per unflip ... present_unflip may be called several times from present_check_flip_window during the same unflip. We can only copy to the screen pixmap the first time, otherwise we may scribble over other windows. The flip pixmap contents don't get updated after the first time anyway. Fixes at least the following problems, which were introduced by commit 806470b9 ("present: Copy unflip contents back to the Screen Pixmap"): On xfwm4 without compositing, run glxgears and put its window into fullscreen mode to start flipping. While in fullscreen, open the xfwm4 window menu by pressing Alt-Space. The window menu was invisible most of the time because it was getting scribbled over by a repeated unflip copy. When switching a flipping window out of fullscreen, a repeated unflip copy could leave artifacts of the flip pixmap on the desktop.
