Yeah. It's weird how things export and go across multiple machines.
I actually had this happen early on in my play testing with DEP. Friend who was playing it instantly knew it was UI zoom. I had set everything up with my windows UI zoom set to 150% and that didn't translate across to other machines.
Also (in Godot) there are a ton of different settings for the viewport that need to be tweaked along with different node settings etc.
I spent almost an entire day getting the entire windows aesthetic tweaked to look good across multiple browsers/ platforms. It was definitely an unexpected fight and learning experience.
