I'm still having this problem about a year later, on ubuntu server (no desktop), with phpmyadmin 4.6.6-5 and php 7.2.15-0ubuntu0.18.04.2.
I suppose that the problem goes unnoticed if php warnings are deactivated, but I'm doing also some development on this server, and the warnings are useful for me.
