Tracking down bugs of this sort is always a process of elimination,
and gathering information to pinpoint the exact circumstances of why
it is triggering.
Next step is to download the exact snap(s) where the problems are
occurring, as this may provide some insights.
I don't run Ubuntu, and I don't use snaps. Can you provide the
download link(s) of the snap(s) that cause problems? If there's
any firefox snaps that don't cause problems those will be useful
too.
It appears there's a searchable "Snap Store" https://snapcraft.io,
but, it doesn't give any download links to the actual snaps which
is rather annoying.
Does anyone know how to get the download link? I have not run
Ubuntu for over 14 years and have absolutely no wish to do so
now either.
Thanks
Phillip
You don't mention if there's any errors present in "dmesg" when
this happens, and so I'm assuming there aren't any?

The same set of Firefox windows and tabs loaded correctly once
switching back to the 5.19.13 kernel image.
The same applies for running the same setup with the home-built "Linux

messages.
Have a nice day, and good bug hunting!
