This offending scanout-disable race condition with a timer\ncan be easily hit when Qemu runs with a disabled vsync by using SDL or\nGTK displays (with vblank_mode=0 for GTK). Refreshment of display's\ncontent shouldn't disable the active display. Fix it by keeping the\nscanout's state unchanged when display is redrawn.\n\nReviewed-by: Akihiko Odaki <akihiko.odaki@daynix.com>\nAcked-by: Michael S.
