Tried to overrelease a framebuffer

[gkye]

I get this warning Tried to overrelease a framebuffer and a black/blank image when trying to apply a filter to an image, this issue only appears on a real device (iPhone 6s) but not a the simulator (The average image size is approx 2-3MB). Is there something I'm doing wrong below.

 func applyFilterOnMainImage(){
    let toonFilter = SmoothToonFilter()
    let pictureInput = PictureInput(image: defaultImg)
    let pictureOutput = PictureOutput()
    pictureOutput.imageAvailableCallback = {image in
      print("Process completed")
      self.mainImage.image = image
    }
    pictureInput --> toonFilter --> pictureOutput
    pictureInput.processImage(synchronously:false)
    
    collectionView.reloadData()
  }

This warning is not present when I using a RenderView but I was wondering if there was a way to remove the black background which is present after the image is applied to the RenderView

I am not sure, But try to change the
pictureInput.processImage(synchronously:false) --> pictureInput.processImage(synchronously:true)

I hope it helps.
