Random dead pixels showing up after liquify
After doing liquify on a smart object/rasterized layer, there are random dead pixels showing up on the whole image and it stays as it is while saving a jpeg/tiff file. Attached is a screenshot of an area of an image after liquify. Can anyone please suggest a solution for this? I have updated PS, restarted it, worked on a different file but still the issue persists. I am currently on CC 2018. TIA
