On sanyo-8100 J2ME racing game, when the player cart is crossing over NPC simple midi sound will be played. When this sound is played the screen flickers for a second. When sounds are turned to off this flicker is not there. I am using SPRINT-API's Player.playBackground() method to paly the sound. Before I have used Player.play() method, in both cases the problem persists. Hlep me to resolve this isssue.
