You can still see like the last frame on the scrolling frame, how do I fix that? and the other frame is like cutting out
Are you using automatic canvas size for the scrolling frame combined with a UI Grid Layout or UI List Layout? If so, what I did was make an invisible object (with visible property enabled) that would expand the scrolling frame out automatically.
If not, maybe try making the scrolling frame have a wider canvas size or decrease the size of the frames.
