"1. The wallpaper is stretched across all sceens, even though the logo, throbber and login dialog only appear on the primary screen."
This is not actually xsplash. That's the desktop background being drawn by gnome-settings-daemon.
The video was interesting. It seems like xsplash is not loading the background image for you. Can you open up a terminal and run:
sudo -u gdm xsplash
And confirm that it does the same thing?
Also, please post the contents of /var/log/gdm/xsplash-user.log here after you've reproduced the issue (e.g., if you run xsplash from the terminal and the problem doesn't happen then don't post xsplash-user.log, logout/login first).
