1. If I open the jpg macos preview
2. Export the jpg into png
3. It loads into godot engine correctly.

When the .jpg image is imported into an image editor and exported as a .jpg again, it works correctly too. It's just that the issue shouldn't be happening in the first place.

I think that Godot Engine is probably mis-interpreting BGR/RGB for the color channels, but needs investigation why.

Wouldn't switching the channels keep the white text white instead of tinting if pink?
Additionally this is how it looks when I swap the red and blue channels it looks like this

I don't think I should rush a pull request but a future task is to compare the results of https://github.com/richgel999/jpeg-compressor loading with https://github.com/libjpeg-turbo/libjpeg-turbo

Help welcome.
