Anybody know how to fix this sprite clipping issue?

[Orcaline]

Hey!

The title probably isn't the best way of describing the issue I'm having. As you can see in the picture below, whenever the player walks down alongside these trees, you can see a one-pixel-wide line overlaps onto the trees. I've tried all sorts of priority levels to fix this, so I don't think that's what's causing the issue. It also happens when entering houses.

I realise that it's almost certainly to do with the size of the player sprite, but is there anyone who would know how to fix this without altering the sprite? Its a fairly minor issue but its been bugging me. Sorry if this is the wrong place for this.

Thanks in advance!
