Yep, I should have closed this. As mentioned on the github thread, the fix was Bitmap font and was pushed live ~4-5 months ago?
Info is available on the Wiki. Bitmap Text object [GDevelop wiki]
You can also see images around my personal settings using BMFont here: Newline in Bitmap Text Object - #6 by Silver-Streak
Although there are a bunch of decent apps other than BMFont too, if you’re looking for those (some mentioned in the Wiki page).
