Summary	05700: amazon, amatelas: lag/desync between sprites and background
Description	hi, i have noticed when playing 'soldier girl amazon' that there is a kind of lag/desync occuring between the vertical scrolling and the static sprites on the background (eg. the silver treasure chests). it can be seen when you either start or stop running forward up the screen (ie. when you start or stop the vertical scrolling). see the attached video to observe the issue. watch for example the silver treasure chests which move out of sync with the background whenever the player stops/starts running.
