Bug Description
I've been testing as follows:
- install chromium (or chrome, or chrome beta)
- open http://
- 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:/
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.

My first guess is that this might be an amdgpu-specific problem. So yes please do try a non-Hades system. I'm running 18.04.2 and can't reproduce any problem using Intel graphics.
Please also run:
dmesg -w
and watch to see if any particular kernel messages correlate with the hangs.
