Public bug reported: I've been testing as follows: - install chromium (or chrome, or chrome beta) - open http://fishgl.com - crank up number of fish to 325 (or as high as it'll go and sustain 60 fps) - after fish are happily swimming, watch them swim for 60 seconds, and count number of times the screen freezes
This was fine (i.e. zero hangs) on 18.04.1 + https://ubuntuforums.org/showthread.php?t=2400400 but not fine on 18.04.2 (i.e. always hangs briefly within 60 seconds) The last four times I ran this, I got 4, 2, 8, 3 hangs in 60 seconds. Each hang usually lasted for less than a second. Some lasted for a second and a half (maybe that was two hangs back to back). Running xclock -update 1 seems to show that the hang extends to other apps, i.e. when the fish hang, xclock also seems to hang. Running firefox in parallel, or a second chromium window, seems to avoid the hang. tail -f /var/log/syslog didn't show any new output during hangs. (There are a lot of gnome-shell stack dumps in /var/log/syslog, fwiw.) I'll try to test on a non-Hades system.
