Combining --trim and --sheet-pack causes sprite overlap #2020

I'm storing all of my sprites in separate .ase files and I'm pulling them onto an atlas whenever I compile. I'm already using --sheet-pack but I'd like to save more space with --trim. The problem is that when I enable both at once, sprites aren't being packed properly.

When I use just --sheet-pack, my atlas looks like this:


This is fine, but there's a lot of wasted space. Especially with large sprites like the flash at the top. If I enable --trim --sheet-pack, now my atlas looks like:


The sprites are being trimmed but they're covering each other up and hanging off the sides of the texture. As an experiment, I tried just --trim to see if it worked by itself:


So I can get just --sheet-pack or just --trim to work, but not both at once. Here is my sprite makefile for reference:

ASEPRITE = "C:/Program Files/Aseprite/Aseprite.exe"
ATLAS = sprite.bmp
DATA = $(ATLAS:.bmp=.json)

ASE = $(wildcard *.ase)
SIZE = 512


	$(ASEPRITE) -b $(ASE) --sheet $@ --trim --sheet-pack --sheet-width=$(SIZE) --sheet-height=$(SIZE) --data $(DATA) --list-tags --list-slices

.PHONY: clean
	@rm -f $(ATLAS) $(DATA)
