Displace filter shifts image? - Shazbot - 09-29-2022
Hi all, so I "love" the displace filter. And I'm trying to incorporate it into my work, but the image shifts to the left the stronger my displace setting? Why would it be doing this? I need to have it displace without moving the image. I'm just using a basic noise texture, nothing crazy. Its done this with every displacement map I've tried.
If I tried to do this for example attachment, my gimp text would move to right or left, rather than be stationary.
Any help is appreciated!

As said elsewhere, the displace filter takes two "map" layers, one for x (or radius) and one for y (or angle). The middle gray (#808080) is the neutral point (such pixels don't move):

You are focusing too much on the tool itself, open your mind, take a break, got some fresh air to see a solution.
for example this picture https://pixabay.com/photos/field-farm-sunset-nature-landscape-2470985/
displaced to have the one below, I got a problem on the side, some transparencies appeared on the left side (yellow rectangle) after displacement, I just selected the yellow rectangle, use the unified transform tool to stretch out, put the result below, move 1 or 2 pixels to the right, no more problem
