charset="utf-8" Display refreshment is invoked by a timer and it erroneously disables the active scanout if it happens to be invoked after scanout has been enabled. 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.
