Testing the Image Blend FX stack from 1LD in an F6 environment. I'm surprised at the performance score from Lighthouse.
This stack has a slider for something called displacement from 0 to 30px. This seems to distort the letters as if they were being displaced by the rough surface underneath. In the example above displacement is set to 5px.
All the items under content blend effects have a result on the final image as can be seen by comparing the different values in this 'vintage' two up set up above.
