For anyone affected in 18.04, I have found in "Settings > Language and Region > Input Sources > + > ... > Other" the layout "German (dead tilde)". This fixes my issue, and I wonder if this is the solution previous posters here were hoping for: the default German layout with only the tilde key behaviour modified.
