问题 We are applying a 'CIGaussianBlur' filter on few images. The process is working fine most of the time. But when the app moves to the background the process produce whit stripes on the image. (Images below, notice that the left and bottom of the image is striped to white and that the image is shrieked a bit in comparing to the original image).
