1.  Enable kde-unstable repo in arch linux
2. Upgrade to latest plasma version
3. Change brightness through keyboard button or power applet

Cannot reproduce with current git master; everything works fine for me.

Did you remember to reboot after upgrading?

Can you try restarting the powerdevil daemon with `kstart5 -- ~/kde/usr/lib64/libexec/org_kde_powerdevil --replace`? Does that fix it?
