The barrel distortion op infuences the image with amount 0. It creates a “border”, as you would expect with a negative amount value. Here is an example: https://cables.gl/p/5d6e4698b566091f7e4721bb?s=9dTJhXTrucRdz8h3
when pushing the amount up, the image looks as expected. seems like the distortion value is offset or sth? I think it was not behaving like that in the past.
