Can you check whether the process "org_kde_powerdevil" is running?

I am having a similar issue Lenovo B570 sandybridge laptop

writing directly to /sys/class/backlight/intel_backlight/brightness successfully changes brightness

Sorry we were not able to get to this yet! Can any affected folks see if it still happens in Plasma 6.3.5 or later? Thanks a lot!
