Chromium Browser started as a regular user:
droid@odroid64:~$ chromium-browser

Gtk-Message: Failed to load module "atk-bridge"
Gtk-Message: Failed to load module "canberra-gtk-module"

Segmentation fault
odroid@odroid64:~$ [21225:21225:0330/190735:ERROR:sandbox_linux.cc(334)] InitializeSandbox() called with multiple threads in process gpu-process

I saw the frame of the browser come up for a fraction of a second before disappearing when starting it as a regular user.
Let me know if there is anything else that would help with diagnosis.
