Can you identify the processes that use the CPU (using top in console for example)?

I was asked to upgrade GNOME to 3.22.0 form 3.20.x. This takes a while. There will be various more bugs.

Let us consider the bug is related to the cpu-scheduler.
Windows uses the "idele-task", there seems to be no process
like this in my Cauldron?

If this is a bug of the cpu scheduler ->
in actual manjaro release (gnome too) its solved,
I donÂ´t know how anyway.....

Garr, completely forgot to push stable updates. I'm pretty sure this was fixed meanwhile.

Related, Mageia could use more GNOME packagers!
