Ubuntu theme problem (Ugly theme)

[ranger1021994]

I have attached screenshots of my current desktop
The themes have gone haywire
I have tried resetting themes using Ubuntu tweak and MyUnity but none of them worked
I had an earlier desktop,system and application backup of the system and restored it using UbuntuTweak but it didnt work

I have so far reinstalled plymouth, lightdm, ubuntu-tweak, myunity, unity and unity-2d

Background :
I was changing my lightdm greeter session to webkit
It changed successfully and i installed xsession-xephyr to test lightdm
However after rebooting the system, everything got messed up.
