Comment 7 for bug 1739468

I could get the messages to stop by selecting quit on some cpu/network monitoring icon at the top right.

once that thing stopped showing up I no longer get the messages. Not sure what the extension was called. Can't turn on off extensions anymore and I don't see anything in the gnome-tweaks program that sounds like cpu/network monitoring so I have no idea what it was.

GNOME shell is such a disaster totally messed up design.
