White Spots after Repairing Device

So when repairing an iPod touch 4th gen and putting in a digitizer/lcd (got from etech parts) the screen when pushed on a little harder than normal creates white dots or discoloration in the screen. Could it be from a thinner type of glass? I had followed the steps on iFixit to repair it and it comes out with white discoloration each time. So that's why I'm assuming it could be a problem with the quality of the replacement part. Its more noticeable around the edges of the LCD rather than the center.

The LCD is getting pressure form the shield. You should check the case it could be bent, or the inter shield is bent.

I dont have anything putting pressure on it. Its when I put heavier pressure on it than normal pressing and it creates a discoloration in the screen mainly near the top. I have adhesive on top and bottom along with some on the sides with breaks where the LCD goes down into the bezel. I also put a small amount of super glue in each corner for extra hold but still creates that discoloration. I checked to see if any small pieces are on top of metal shield or below LCD and nothing.
