I tried fixing the masks' position and size but it got worse. And playing with position coordinates and size actually blurred the only layer that was sharp - Layer 1. All PNG layers above - clipped under the two masks that show glowing text - are blurry. May be the fact that the text shows rotated under an angle is not OK for the preview.
Layers: Layer1.png, otg.png, LIVE.png, LAyer2, 3vpr.png, DNESA.png that show blurry (P.S. The are not meant for RETINA DISPLAYS)
