In my paper2d game I've noticed some heavy rendering lag even with only a few sprites in the level. Here's a picture to show what I mean, and in it you can see that as the player moves to the left, the background tree jumps big distances as it moves to the right. When I turn my engine scalability settings to very low, the choppyness is reduced. Any ideas on how I can improve the performance so that the background moves smoothly as the character moves around?

Also of note, none of the sprites use translucent materials, so I don't think it has to do with the translucency sort priority.
