When watching videos or scrolling through websites, I see a horizontal line going down the screen like the page it refreshing. It kind of looks like those old TVs where you can visibly see the screen refreshing. I have seen the same thing happen on two different laptops running Manjaro. A Thinkpad and an ROG laptop. The Thinkpad uses Intel integrated graphics and the ROG laptop has a Nvidia GPU and Intel integrated graphics. Both of them are using the modesetting driver for graphics.
I have tried switching to intel graphics drivers (suggested by a forum I found on the Arch Linux website). (I am using modesetting now) When I did that light display manager does not start and X would not start. I have also tried adding tear free to the configuration files as suggested by the Arch Wiki but that did not help. I have also tried adding kernel parameter i915.enable_psr=0 which the Arch Wiki said might help but that also did not help.
I found a solution in this forum for the browser but this issue happens outside of the browser too. Including local video files. I do not know how to fix this and would appreciate some help. Thanks.
