Eliminate line when scrolling in browser

[penglix]

Thank you for your reply, firenice03!

Unfortunatey, I don't have the same chip. According to the program "Lite System Report" I have:

Explanation: VGA compatible controller
Product: Haswell-ULT Integrated Graphics Controller
Company: Intel Corporation

and

Explanation: 3D controller
Product: GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M]
Company: NVIDIA Corporation

What can I do? That line is very annoying. I also have it when scrolling in a pdf file not just in my browser window.
