I'm not seeing the problem on my Ubuntu 18.04 desktop. I configured Emacs master 
this way:

./configure --enable-gcc-warnings --without-gsettings --with-x-toolkit=lucid

And I ran it this way:

src/emacs -Q --fg-daemon
lib-src/emacsclient -c

I also tried --fg-daemon and couldn't reproduce it that way either.

What is your native screen resolution and how are you setting your font scaling 
factor? I used gnome-tweaks to set my font scaling factor to 1.30. My xrdb 
output says:

$ xrdb -q | grep dpi
Xft.dpi:	124.7998046875

My native screen resolution is 1920x1200 and my native Xft.dpi is 96.
