Summary	05703: dblewing: lag/desync between sprites and background
Description	Hello I've noticed desyncs between sprites and background Most noticeable are the craters Is it safe to report others games with same desync problems ? I think devs are aware of them and I don't want to bother them or be a "request" guy but it should be nice to report them as a reminder especially when games have no gfx flag Thank you
Steps To Reproduce	Just play and move left right quickly
