Nothing that would invalidate warranty
But then, sometimes I wonder if I am just convincing myself, rather than face the ball ache of trying to get it returned and find a better one...
It's difficult to describe, but I will try...
The screens front has a tiny gap between it and the frame all the way around - not the silvery bit of the outer frame, but the "inner" support frame, for lack of a better way to describe it.
It can even be difficult to get a fingernail in there.
But if I apply gentle forward pressure by catching on to that, the bleed is reduced somewhat.
So wedging something quite flat (even a credit card too thick for example) as far down on the left as I can, it seems to help.
I have not found what I can use as a more permanent solution - finding something both that flat and still quite firm is difficult.
Not sure if any of that made sense.
In a nutshell, it simply seems as if the screen front cover is simply being held on with a bit too much force in some parts - in my case, the bottom left.
