I am using a macbook pro (2880x1800 on a 15" screen) and a 4K 27"
monitor, and I went through this a while back.

Having said that, while I use various TDE programs, I don't use TDE's
window manager, so this advice may not work for you.

I solved a lot of problems by putting

    export GDK_SCALE=2

in my ~/.xprofile, which gets read by /etc/X11/xdm/Xsession,
/etc/tde/tdm/Xsession and /etc/kde/kdm/Xsession (at least on my
system) and helps a lot of GTK3 programs look reasonable.

It shouldn't hurt (too much) to give this a try.  I'd be interested in
knowing how it works out.

It is too bad that so many software designers assume that screen
resolutions would be 90 - 100 DPI for all time.
