Description

The "chromatic abberations" plugin does not provide a consistent correction for image zoomed-in. Its behaviour is dependent on the position of the image in the preview window.

(However, exported images are okay and automatic CA is applied correctly.)

Se the attached screenshot.

i plan to rewrite that at some point. this code was never meant to run on small resolutions and thus breaks for previews.

Just to add a small information: chromatic aberration display changes depending on the screen position of the image. I mean: if you move the display portion of the image with the mouse, the CA changes too.

I don't know if this can be useful for the debug
