I just bought second hand a Nexus 4 with 4.4.2 stock. I have noticed that despite having the "optimization WiFi" unchecked notifications are slow in coming. When they had selected were minutes or until the screen lit. 
WhatsApp also have problems with the LED lights do not always and sometimes I get blank screen shows (only app that gives me any problems). 
Does it happen to anyone else? Can you solve with custom ROM? Any word on 4.4.3?

The WiFi is normal, you can try looking in the same Whatsapp recent connections from your contacts, which appear after a minute. 
The blank screen is a thing of Whatsapp, not mobile. And light, consider installing Lightflow.

The notifications with delay start or stop passed optimization Wifi, I tried at the time. 
 
Do not know if my problem is itself mobile system or the truth ... = S 
 
What the snapshot blank when entering a Whatsapp app thing is, curiously after "optimized for android 4.4" the app do worse
