It is not easy the video so I will the send 4 images with different zoom.
A)There is a note that is misplaced.
B)That note is in its place now. Accidentals start moving awkward
C)Accidentals getting worse.
D)Notes out of the staff too close, they share "the line". Flag of some quavers too high (touching the head of the note). Some accidentals completely misplaced.
Besides the thickness ot the lines [which indicate the position of the note out of the score] varies according to the zoom, however the 5 lines of the score behave properly in every case. Finally the beam that joins notes doesn't behave properly in some levels of zoom.
My English is very poor (if I don't make myself understood just tell me). I hope it helps
