Does anyone have an idea how to fix this?

In my opinion it is not a good idea to bind "RET" to `evil-ret' in
insert mode. The reason is that many modes may have their own
implementation of some return-key-magic, so at least, `evil-ret'
should preserve the default binding in insert-mode (in addition to its
own magic).

For the short term (until we decide what to do) you can do two things:

1. customize `evil-auto-indent' (set to nil) to prevent automatic indentation, if this is you problem.

2. unbind `evil-ret' in insert-state, e.g, (define-key evil-insert-state-map (kbd "RET") nil)

Anyway, you're right, having a binding like `evil-ret' active in
insert-mode without taking care of any other binding is probably a bad
idea. Thanks for pointing this out.
