I am concerned about the first four columns of dots in your first block. They shouldn't be lighter than the rest.
Right before posting the pictures it did not apear this way, maybe i fried them somehow? but anyway the 1st row have been all black even whitout this error. (so this does not cause the problems)
Try putting some pressure on the black trim that surrounds your LCD glass and see if this condition changes. You could have a loose connection between the LCD display and it's pc board.
