I'm guessing you already know more about X than I do (I didn't know about
xhost until just now :) but here is what I do when I'm stumped:

I keep an unprivileged user named "tester" with almost nothing in his
home directory:  i.e. no .local or .config or .cache or .dconf/.gconf
directories, etc.

If something works when I'm logged in as "tester" but not as me, I start
copying the subdirectories in "tester"'s home directory one by one into
my own home directory until the broken feature starts working again.

(Of course, I move my own subdirectories out of the way before I do this.)

The last few times this has happened to me, the problem was some sort of
strangeness in my ~/.config/dconf/user file.
