This offending scanout-disable race condition with a timer can be easily hit when Qemu runs with a disabled vsync by using SDL or GTK displays (with vblank_mode=3D0 for GTK). Refreshment of display's content shouldn't disable the active display. Fix it by keeping the scanout's state unchanged when display is redrawn. Reviewed-by: Akihiko Odaki Acked-by: Michael S.
