No, not the same. See attached screenshot of the top-level window of my 
application, showing the top of the accounts tree. This screenshot was done 
on an Arch Linux system, so the little expansion arrows are visible, as 
they should be. On the Void system, they are not visible, but clicking the 
blank space where you would expect them to be does expand accounts with 
children. The problem is that you can't distinguish those with children 
from those without (leaves). This is a show-stopper for me.

I use whatever the default is. According to the Arch Wiki, Adwaita is the 
default for Gtk+3, though it's not clear from their language whether that's 
specific to Arch or a default set by Gtk. In any case, I tried forcing the 
Adwaita theme on Void and it made no difference.

Thanks for trying to help.
