How to avoid flickering between pixel sprites when slowly lerping zoom?

This is what it looks like:

I am lerping the camera’s zoom with this function in a controller:

func cam_tween_zoom(start_zoom: Vector2, end_zoom : Vector2, duration, transition : Tween.TransitionType, easing : Tween.EaseType): #  tweens the camera between two positions

	var zoom_tween = create_tween()
	zoom_tween.tween_property(self, "cam_zoom", end_zoom, duration).from(start_zoom).set_trans(transition).set_ease(easing)

and then setting the zoom value itself with

self.zoom = cinematic_controller.cam_zoom

I noticed that turning off pixel snapping transforms fixes this, but I don’t want to do so to keep the retro pixel art style of my game. Is there any other solution?

I’m aware that it has something to do with having a non-integer zoom level, but as i want to be able to zoom smoothly and to any point i like it’s not viable to limit the zoom level exlusively to integer values.

Lmk if any more info is needed

Why can’t you turn pixel snapping transforms off? The look should stay the same it will only affect how Godot renders specific pixels a bit. Without turning that setting off I don’t really know of any other solution for this behaviour.
