My laptop is about 2.5 years old. Now I am starting to see red dots on certain shades of colour (mainly dark colours, blues and blacks), and it is not limited to certain pixels, because when you move a window around, the red dots move with it, staying on the certain shades of colour.
Is this a problem with the LCD screen, or is it the GPU? Is there a way to determine this?
It is clearly not a driver issue, because it happens in Linux and Windows, and my Windows setup has not changed prior to the issue starting.
