Andrea, this new kernel looks promising. Linux millbarge 5.4.0-17-generic #21-Ubuntu SMP Fri Feb 28 16:18:44 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Unfortunately I didn't check the reproducer before rebooting: the error message I get with it now suggests that it might not work any more. However, this visualization https://platform.leolabs.space/visualizations/leo sure feels like it would have the heft to reproduce the problem. It worked fine for me in both firefox and chromium-browser: sarnold 4987 14.1 3.0 3042112 495860 ? Sl 03:42 0:46 /usr/lib/firefox/firefox sarnold 5070 7.3 1.8 2651760 293108 ?

An uptime of 30 minutes is perhaps too short to declare success but this is certainly promising.
