After cloning https://github.com/Skeeve/SDK_6.3.0 on my Mac and switching to branch 5.19, git status shows all (or at least a lot of) files as modified.
It's not the line endings and also (I think) not the filename case, as there are real differences shown with git diff.
I have no clue how this could happen.
Just tried it in a debian docker container and I do not face the issue.
Maybe someone here has an idea?
