If you updated and that green line showed, why not downgrade then see if the green line still exists. Then it's definetly a Hardware issue

Also, I know that you don't have the issue

[Manny_Cavalier]

Yeah, I don't have this issue. Just want to help other members here that have this problem.

Regarding what you suggested, there is no way to downgrade once you already pushed the newer version.

[pham_hni]

There is a way, just make sure that the binary version you're downgrading to is the SAME as the binary version you currently have.

Where are you going to get a copy of your previous version?
