@maxmeyers Hi. Is this issue already resolved? I made a simple camera app sample with FastttCamera, but this issue(use memory gradually and unreleased) occur while filtering.

This is my Sample (written in Swift) https://github.com/masuhara/FastttCameraSample

Could you check this high memory issue?
