On left-handed interface the bottom panel covers zoom buttons.
Zoom buttons overlap bottom panel since 4.14.0
Release notes mention "improved layout of the bottom main screen functions panel" but it seems there's a problem with my configuration of panel hiding. When zoom buttons are visible or auto-hidden, the bottom panel is of a different shape and the zoom buttons overlap it (only after the panel auto-hides at least once, though - it's okay for the first 2 seconds after app start).
