Fix main thread block issue after manual rotation.

Currently, when rotating on a static page, there is a problem that the screen
stops for about 10 seconds from the second rotation. It seems that the main
thread is blocked during the dequeue process when a screen lock occurs while
performing manual rotation again on a previously used buffer.
We can avoid this problem by forcibly refreshing the screen once more after
manual rotation is complete.
