My laptop is thinkpad T450s and there is very bad screen tearing when I move windows around or when I watch videos. My CPU is Intel HD 5500
with integrated graphics(core i5).
I looked around but I only found a solution for Ubuntu. I found same question and this is the answer.
I am not sure if that can be used for elementary OS. It didn't fix anything. Is there a solution for screen tearing on elementary OS?
I have also tried this video and it didn't work.
EDIT: It does work, you just need to restart, which I forgot to do. See solution below.
