Works here, what's your Qt version?
I'm not qt5 (5.4.0-3)
Oops, typo... I'm on qt5 (5.4.0-3)
Do you need more info or can this bug be confirmed?
Thanks for the update, changing status.
Hold on. I can't reproduce this anymore with latest updates from Arch. (KDE Frameworks 5.6.0 + systemsettings5 5.2.0 + Qt 5.4.0-3)
Nope, ignore my last comment. I still can reproduce it. I couldn't reproduce it with Nouveau, but I can with NVIDIA drivers.
