Public bug reported:
Just now I was watching some video in Firefox. I popped over to another
virtual workspace for a few minutes, and when I popped back to Firefox
it had gone. The same thing had been happening all week (I installed
fresh Ubuntu-22.04 last week) with Chrome, Firefox and Thunderbird.
This time instead of shrugging it off I looked in the logs, and found
this

I know it's saying those three entirely unrelated applications had
suddenly decided to swallow all the RAM+swap on this laptop of mine -
but the very same apps didn't act like that last week under
Ubuntu-20.04, so I suspect something else is going on
I can't say they hadn't swallowed all the RAM, but there is ZERO sign of
a system on the verge of collapsing - everything has been screaming
along just nicely - no sign of the "staggering" you normally get when
the OS is heavily into swap.
However, now that I look I see my 16G laptop only has 1G swap??? I just
let the Ubuntu installer do it's defaults - but it used to auto-choose
1xRAM or 2xRAM - what's with this 1G swap? Could that be related?
