When the background of the theme is set as a video, the video is not visible.
Only the black screen and the lyrics written are shown.
It works normally when the theme's background is solid.
I can't see the screen even when I load and play the video.
I can only hear the sound on the black screen.
It worked before, but when I turned off the program, it suddenly doesn't work.
And the button to make the background transparent doesn't work either.
Only the same black screen is shown.
