You installed Docker Desktop. Docker CE is inside the VM. All we see is that the qemu process (the VM) uses 5 CPUs. Which probably means processes inside the VM use lots of CPU resources. Most likely your containers or more specifically processes inside the containers. So first should find out which process, then you can find out why.
Yep, I thought so, however I didnt see anything conerning inside of my containers.
I am using exact containers on my laptop (ubuntu 22.04.5 LTS, Ryzen 3 5300U (8) 3.9GHz) and never experienced such issues on it.
So while the sum of the CPU usage of containers are normal, you still see 500% CPU usage of qemu, right?
Do you have some Docker Desktop extensions or Kubernetes enabled? Those could use the CPU, but those are the containes not shown by default unless you enable showing system containers (to see extensions) and Kubernetes containers
