Hi there, Zepce -
Thank you for writing in to the Lenovo Forum - happy to have you here today.
Try updating the video driver. Also, check if issue persist in safe mode or not.
Update us how it goes.

Hello, I also have had this issue. It's not just the upper portion of the text, it's specifically when I am browsing the internet, there are blocky distortions (black or white or other shades) covering portions of lines of text. I followed the suggestion here of installing the latest video driver (I bought my laptop about a month ago, though) and it didn't fix the problem. Also, it's happening in firefox and I'm wondering if there's some narrow, specific cause of this. It doesn't happen on other laptops, though. Thanks!
