Hi Andy,

Well, it appears to be a problem causing the deflection to fade as the
display gets into the more positive range. The (-1,-1) bottom left
corner starts out OK and fades off as the values get close to (0,0).

What are you driving this with? A board or a monitor signal generator?
Bad edge connections are always suspect but pretty sure you will have
checked those carefully
