Horizontal line on screen?

Thank God I’m not the only one having this issue. The line on my screen happens when I move the camera fast or spin my Sims around in cas. I got a new laptop after Christmas and I saw the line, I just ignored it thinking there was an issue with the installation. But then I took that laptop back (it was falling apart- manufacturing issues) and I got a new one. I still have this issue, I have NVIDIA geforce gtx. I wouldn’t worry about it, I’ve adapted to ignore it by now. Your laptop should be fine to download any new packs, I’ve downloaded 4 packs while having this problem. Hope this helps!
edit: I just realised that you are using the Sims 3, whereas I’m using the Sims 4
