Blur issue in lanscape

After take a photo in landscape, then turn on blur, the blur position is incorrect, especially in the left bottom.

I found that all the corners have this issue when the image is landscape.
I think it is because the image is rotated according to the orientation, but the blur layer not. So, when you tap on the blur area in the left bottom, the image is clear on the right bottom.
Anyone can solve this issue?
