Hello
Recently, my Swift 3 has had black vertical lines across the screen that don't move and persist no matter what I do, i.e. change resolution and refresh rate, boot in safe mode. It happened during a Microsoft Teams call and I haven't found a way to stop them since. Also occurring is a whit blur that slowly accumulates on the screen and eventually makes it difficult to see anything. This goes away when turning the monitor off and then on again, but will start to accumulate again with time. This only seems to happen when the screen itself is displaying something white, i.e. a website with a white background. Any help with this issue would be appreciated.
