Problem with ovelay!

[yours.mukul]

Earlier I posted a problem with Alert module (https://forum.magicmirror.builders/topic/5013/problem-with-alert-module/6) and I was suggested to check out Elements in dev mode. And now I found the target point.

The problem is “overlay”. Either for Alert or while brightness of screen.
I twerked some integer values and I find that the overlay starts after leaving some space from left portion and giving it the buggy look. But still I can’t find the solution. I shall be thankful to the community if you can give me some solution.
I’m uploading some pics for better understanding

Checkout that I changed the width, and you can see the overlay starts after leaving some space.
It happens for Alert as well as Brightness
