CSS div background-color bug on chrome?

Question

I'm having trouble setting the background of a div in Chrome Browser. If you see, I have a small lighter grey box that I didnt implement and give style. It appears randomly and moves and reshapes as it wants. It doesn't happen on Safari or on Firefox and I can't understand why or either how to fix it.

My problem is quite strange. I have the following code:

div className="row competition">
   <div className="col-lg-6 register-answer">
       <div className="compet-content">
           <input type="text" className="form-control answer" id="usr"/>
           <input type="text" className="form-control email" id="usr"/>
           <button type="button" className="btn btn-primary">Enter Competition</button>
       </div>
   </div>
   <div className="col-lg-6">
       <div className="pic">
           <img src={CompetitionImage} alt="Competition Image"/>
       </div>
   </div>
</div>

Edited (CSS classes):

.col-lg-6.register-answer {
    background-color: #adadad;
    .compet-content {
        width: 100%;
        height: 100%;
        input {

        }
        button {

        }
    }
}

I'm setting the backgound-color on 'register-answer' class but I tried at every div and the problem is always the same (it only happens on chrome). I have a screen recording also for you to see: https://drive.google.com/file/d/0B9yzCbrCAKvKRVE3VmNJNmhqLVk/view?usp=sharing

I'm also having this problem and found this: http://www.parallaxinfotech.com/blog/addressing-css-artifacts-left-screen-chrome

Tried the solution... -webkit-transform: translate3d(0,0,0); in the rule where I specify background-color (body, in my case) and that worked. Still looking for a better solution.

UPDATE: Looks like this is a Chromium bug. If you want to solve it for all your visitors, the hack above seems to work. If you want to solve it for just you, you can go to chrome://flags/#enable-gpu-rasterization and enable GPU rasterization. I imagine this bug will be fixed by the Chrome team soon enough, so I decided not to use the hack.
