I observed this issue when opening a file selector in Chrome and Firefox.
It took about 10 seconds to open a file selector, and moving to a subdirectory
also took several seconds.
This issue didn't occur in other applications such as gedit and Files, so it
may be different from the one discussed
I also had the same problem on Zorin OS, and the suggestion from #18 fixed it.
It's been a while since I tried that fix, but the steps are as follows if my
memory serves:
1. `sudo apt remove xdg-desktop-portal-gnome`
2. Log out and then log in
```
$ cat /etc/os-release
