Scroll To problem

I made Scroll To events like this:

System: Every tick -> Scroll X to player.x

Player on the floor -> Scroll Y to player.y-140

But when player's sprite is jumping i get this sometimes.

It's a small little pixel that appears randomly (after 2-5 jumps)

How do I fix it?

.capx

up

Set scroll Y to floor(player.y) - 140.

Set scroll Y to floor(player.y) - 140.

Oh, big thanks!
