Itch display size issues

For some reason I can't get my display size to cooperate on Itch! I ran into this issue last LD, and I never found a fix 😭 At least it's not game-breaking like it was last time... but has anyone dealt with this before?
I have the display size set to 640x360 on Itch and in my Godot project settings. Seems to work fine running it in Godot, but for some reason it's a lot smaller on Itch.
