Fix mode without avatar

It seems that this mode didn't get much love when I added the bubbles so
it was quite broken. This patches removes the bubbles and fix the
alignment issues when using this mode.

We probably should rename it to compact mode in a follow up commit (but
not this one so we can backport it to the stable branch).
