Comment 21 for bug 1804786

I have 3 computers running Ubuntu desktop edition:
An old HP LapTop, 19.04;
An old Apple iMac, 18.04;
And a VM, 18.04, running on my main Ubuntu 16.04 test server.
All 3 have the issues, with one main difference in the 19.04 verses 18.04 "play again" stimulus response.

Attached is the "lspci -k > lspcik.txt" information for all 3 combined into the one file.

Note: I almost always jump to the last few seconds when playing the video, to save time. I have never noticed any difference in system response for subsequent video playing when jumping to near the end verses letting it just play to the end.

For: "yelp help:gnome-help": There are sometimes a few of these, and more on the HP:

Xlib: sequence lost (0x100f2 > 0xf4) in reply type 0x0!

Responses from a new terminal execution of: "yelp help:gnome-help":

0 <= integer N <= infinity (actually tested to N = 4)

Do N times{
  wait > 60 seconds after the video finishes
  play the video again.
  The video plays correctly.
}
wait < 57 seconds after the video finishes
play the video again.
The video plays correctly on the iMac and the VM, both 18.04, but incorrectly on the HP, 19.04.
Now wait either less than 57 seconds or more than 60 seconds and then play the video again.
If the wait was < 57 seconds then the video plays incorrectly now and thereafter, no matter the time waited between plays.
If the wait was > 60 seconds then the video plays correctly now and thereafter, no matter the time waited between plays.
