i have noticed one thing more with the transparent background , dont know if the transparent background supposed to be this way or not .
while sliding the image to unlock i see the theme's background not the one i am having on my desktop and it also take a pause before unlocking .
like if i slide the image to unlock it takes few seconds first to show theme's background and then it unlocks .


edit : it shows my desktop but under the theme's background.
like first my slider image then under it the themes image and then under it my desktop :$

look at this


number 1 is my slider image
number 2 is theme's background/desktop image
number 3 are the queen beecon widgets i am using on my desktop
