You can try to apply the blur to a white rectangle to see how it reacts.\r\n![defocus_bug](https://cloud.githubusercontent.com/assets/9614046/21752088/bf25e5ea-d5d2-11e6-9825-9111d12a353f.jpg)\r\nAlso it will need a few tricks to extend the color to not have black borders in the blur. (in the screenshot I did this).\r\nI think it's better to leave it as is for now and maybe look into a different algorithm latter. Or maybe someone as a hint on how to fix this.\r\nSorry..."}}
