Lars, thank you for grooming the bug tracker.

I faced this bug as unrelated to HiDPI display and namely in KDE. Help 
and open folder toolbar icons have normal sizes in Gnome.

I do not have a VM with latest KDE plasma and Emacs, but I had to add 
the following to my init file on Ubuntu-20.04 focal (latest long time 
support release) with Emacs-26.3:

   '(icon-map-list
     (quote
      ((("etc/images/diropen" . "n:folder-new")
        ("etc/images/help" . "help-contents"))
       x-gtk-stock-map)))

Warning: do not try to to create such structure from easy customization 
UI. Alist pairs will not be wrapped in a list, invalid values will not 
be e.g. rejected by setter and you will get semi-broken emacs spitting 
icon-related errors on attempts of various actions.

The problem is that KDE does not provide these non-standard icons in 
sizes suitable for toolbar, Gtk takes larger versions while other icons 
have normal size.
