Display Issue - Horizontal blue lines in application windows

As you can see from the image below I have blue horizontal lines appearing within my Chrome application window


2019 Macbook Pro 16


The application is the latest build of Chrome Version 80.0.3987.163 (Official Build) (64-bit)


It has happened 3 times now - each time appear to be after the laptop has been left running overnight.


Not it is not the full display affected only the application window. I've also only seen this in the chrome browser (I've also posted this to the Chrome support site) it sometimes goes away simply by killing Chrome but this time required a reboot.


Anyone seen this before - got any ideas??




MacBook Pro 16", macOS 10.15
