THE IDOLM@STER SP: Perfect Sun [ULJS00167] works pretty much same way. Crashes in the main menu if you wait a while and at least one rhythm mini game is unplayable due to warping icons. Menu/text transparency problem can be avoided by enabling shaders and stencil test. Otherwise seems playable.
Info level logs of the crash and mini game.
