Ok, it sounds like plymouth is working as expected when called as 'plymouthd --mode=shutdown'. So I think the fixed splash screen that you see on shutdown is *not* due to plymouth. It may be a bug in the video driver, or it may be something that lightdm is doing on shutdown, I'm not sure. Reassigning to lightdm for further triaging.

An unclean shutdown of the system, whether due to a hang or a power-off, can cause corruption and data loss on your filesystem. It will not damage the hard disk itself, but you can lose data. Usually the risk of data loss is very small.
To further reduce your risk, when this hang happens you can try to use the SysRq key (Alt+PrtScn): SysRq+S to sync the disk, SysRq+U to remount read-only, and SysRq+B to reboot. If this sequence *doesn't* let you reboot, then that further tells us that the kernel has crashed, pointing the finger strongly at the video driver.
