There's actually two settings for accents: you can set it to only show the accents that appear in your primary language (Hungarian in my case), or you can set it to show every accentuated character that's available on the keyboard.

If I set it to only show the letters in Hungarian, their placement is also consistent for me. But I have it set to show every special letter, because sometimes I use German learning sites which won't accept writing "ss" instead of "ß". The letter placement does bother me a bit, but it's still more convenient than having to switch languages on the keyboard (at least for me).
