Bug description:
[Impact]
* gnome-system-monitor 3.36.1 is the latest minor update in the 3.36
series
* it fixes one bug (https://gitlab.gnome.org/GNOME/gnome-system-
monitor/-/issues/142), and includes translation updates for a few
languages, but these won't impact the package in Ubuntu because it
uses the gnome language packs
[Test Case]
* In gnome-system-monitor's preferences window, in the resources tab, set
the update interval to 0.5 seconds
* Open the resources tab and watch the network traffic graph while
generating incoming and outgoing traffic (for example by running speedtest-cli)
* Expected result: outgoing and incoming traffic on the graph is consistent
with the actual traffic
* Actual result without the bugfix in 3.36.1: the graph shows null outgoing
and incoming traffic, even though the totals seem to be updated in the labels
below the graph
[Where problems could occur]
* Given the one and only code change in this update is a one-liner
that adds a cast to double (https://gitlab.gnome.org/GNOME/gnome-
system-monitor/-/commit/3e916c4ee21cede8465e9378fa07e9a71a472c2f),
regression potential seems fairly limited. Looking at the code in more
details, the change is in a function that is used only to draw the
network traffic graph, it's not common code used to draw other graphs.
So verifying that the bug is indeed fixed should be enough to be
confident there are no regressions. Testing should be carried out with
various values for the update interval, both integers and non-
integers.
* As mentioned in the impact section, this update includes
translation updates, but those shouldn't apply because translations
for gnome-system-monitor are shipped externally as part of the
language-pack-gnome-*-base packages

3) There should be a graph drawn with the info about my network usage,
as well as number on the download/upload speeds.
4) Pretty much nothing happens. It calculates how much data I've
downloaded/uploaded since the OS was booted, but that's it.
