Weird indentation issue on emacs

I’m getting some very weird and disturbing indentation issues when using emacs…

This happens only in sclang, no other modes. Is anybody else getting anything similar? I’m on v 31.0.50.

Solved. Turns out it’s visual-wrap-prefix-mode that messes with the indentation on scel. Only happens with supercollider, as far as I can tell…
