Xperia Z Android 4.2.2 problem

[Florin1]

I have just installed 4.2.2 on my Xperia Z (Netherlands)

When i first start up the phone the bottom bar is transparant as it should be.
Once i press my lock button and unlock it again, i enter my pin code.
The bottom bar is now black as before. How can i fix this?
Rebooting the phone does not help!
Thanks for reading/helping.

EDIT:
The bar is now always black, even when i start up the phone.

Try a repair using SUS but back up everything before doing it.. if you are using dark background you wont know if its transperant or not

Try to apply the default theme again. I've read that this is working on some devices. Then, you can change the wallpaper again

The problem was a wallpaper app, Mine was called something like backgrounds HD.
Just remove the app and reboot the phone fixes this.
Got it from XDA forum btw.
Thanks for helping anyways
