Default [Q] Since 4.3 update: removing s-pen no longer turns on screen

Ever since the 4.3 update the screen won't turn on when I remove the s-pen. This was never a problem before.
Is there anything I can try before I reset the device?

I've tried different launchers, turning on/off the Tasker profiles which involve the pen, different apps (such as Note Buddy), etc. without any luck.
The phone knows that I removed it (the Tasker profile starts and the standard sound is heard), but no screen.
