I'll try that next. In the meantime here's another observation:

I started a firefox session on a remote host (via ssh -X) from
the Pi. Once the X window opened up the Pi slowed to an unusable
crawl, but the load notation in the top-right menu bar stayed
under 25%, a top window reported less than 200 MB of swap in use.
In this case the machine didn't lock up but was basically useless.
It took a few minutes to bring a window to the foreground.
The page I opened was
https://www.ssec.wisc.edu/data/geo/#/animation?satellite=goes-west
which is a single frame of weather satellite imagery. No animation.

That seems to point toward a problem with the X server on the Pi.
BTW, I'm using the "experimental GL desktop".

Does anybody else have trouble opening the page?

Thanks for reading!
