Why do blue lines appear on my screen?

[JCarl34]

Recently, with the update of the driver of my intel gpu (intel hd graphics 620) I am having this type of problem almost in anything of my second monitor, before installing the new driver nothing happened, now it is very annoying, even when I play I can notice it. What's going on?
