This mod won't fix it. This only serves for achieving full combo in each song in the game, not graphical issues. If you want to have to downgrade the resolution, use this site to get this modded version of the game:
BandoriMod. I haven't tried it myself since I don't have a problem regarding anything suddenly disappearing during live, such as the lane disappearing in the game like yours or the notes lane. It only downgrades the resolution in order, for example, your device can handle rendering the lane hopefully. This, however, doesn't AP a song but choose your own resolution, iirc. Make sure you have your transfer code ready before using it, so you won't lose your account.
