Athom mixes the descriptions “CPU usage” and “System load” or “Average load”  
 → CPU usage indeed cannot exceed 100%  
 → System load can reach 300% or more

Proof  
Mobile app:

My Pro 2019 does not have CPU figures, but it does have this “average load”; however, this is very different from the above % values:

There is also a handy monitor app available: [SysInternals](https://community.homey.app/t/app-pro-sysinternals-shows-homey-s-system-internals/78650)

A possible cause can be “chatty” devices, same as can occur with z-wave.  
Certain Tuya devices are known to ruin / clutter the zigbee mesh by emitting way to much messages; probably certain Niko device types do this as well.  
I’ve also read about a dimmer doing this.

Homey just tries to keep up, wich can cause these higher system loads.

BTW a CPU running at 100% is nothing weird, it only throttles down when there’s less to process, to save energy .

Depends on how you paired them.  
But the description sounds as a range problem, the roller shutters seem to be on the edge of the range. And the range can always vary a bit, due to interference.
