Is Steam mining in the background?

Question

Steam

In general, I am not very fond of games, especially Steam. And then I decided to install it and ran into a strange phenomenon - Steam in idle time (from running programs: Steam, Firefox & Telegram) loads the i5 processor by 30% +. Moreover, Steam is in idle time, i.e. does not install / update anything (by the percentage of the disk load on the screen, in principle, it can be seen).
Is there a proper explanation for this? The first thing that comes to mind is stupid CPU mining for a percentage of PC power that is invisible to the inexperienced eye.

I'll write here, maybe someone will come in handy, otherwise I've been looking for a solution for a long time. The problem is in the nvidia driver, or rather in the "nvxdsync.exe" process. ХЗ maybe it conflicts with "SteamService.exe", but renaming "nvxdsync.exe" to "nvxdsync1.exe" fixed the problem, though the driver panel stops working ... But in my opinion this is not so scary anymore! And so that the panel does not load the context menu, it is also advisable to rename "nvcplui.exe"!
Paths for the above files:
?:\Program Files\NVIDIA Corporation\Control Panel Client\nvcplui.exe
?:\Program Files\NVIDIA Corporation\Display\nvxdsync.exe
Do not forget to kill them in the manager before that!
Well, or even simpler, we are looking for the old version of the driver and install it, we go together to the nvidia website and fuck their brains,
