Forum Post: osd window scroll problem

i do some other test ,and found that if i linked the osd link after the swms ,when i change the osd window startX for rolling(+2),before the osd window would have a shadow flash once for change .but if the OSD link is before the swms link ,it will not have the shadow flash,but when it is rolling for horizontal,it is still flashing.

so whether is there a way to fix the problem？
