at one core

Hi,

if i switch on the option "use all cores" in the behavior tab, the programm
opens 32 threads, which is the number of the available threads, but all of them
running at one core (visible at ksysguard and htop).

System is Opensuse Leap 15, fresh install, only amdgpu-pro for the opencl stack
is installed. Digikam 5.9, KDE-Plasma 5.12.6, KDE-Framework 5.45.0, Qt 5.9.4.

Thanks and regards!

This behavior is reproducible at my side.
But was not observed at Kubuntu 18.04 with Digikam 5.6
