I’ve not discovered something helpful across the web for this, so posting as a query right here.

Machine is: MSI Gs66 Stealth SFS laptop computer

I gotten three skinny black strains (over the mouse) first on the underside of the display. Right now they’ve “upgraded” to extra strains, which really mirror the color across the middle of the monitor (white on the photograph, however white components transfer if you transfer a window above them).

A number of updates of firmware and exams decided that

* The strains don’t seem in BIOS

* The strains don’t seem when graphics are switched to discrete GPU totally

Makes an attempt to replace Intel Graphics driver did nothing (MSI obtain one declined set up because it was “not validated for the pc”, whereas generic one didn’t remedy the problem on a clear set up).

What might be the perpetrator there?
