A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.
(gd_gl_area_draw/gd_egl_draw)
if (dmabuf) {
if (!dmabuf->draw_submitted) {
return;
} else {
dmabuf->draw_submitted = false;
}
}
So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.
