@6th: the request was to report this upstream, however I have just tested it with system monitor 3.28.2 on Fedora, and it works just as it should: with upside down pyramid the highest cpu% is on top, the lowest on the bottom, and with normal pyramid the highest cpu usage is the last.

The cpu % column has the two confused. When showing an upside down pyramid the largest values should be at the top (which is how the other columns work, e.g. the ID column). Instead the smallest values are at the top.
