when i use it on a android device full screen, i sometimes get starnge errors at the top and right hand side of the screen.

i think it is trying to blur pixels from the desktop or other image, when its at the edge of the blurs processing image.

is there anyway to make sure the buffer is empty before bluring?  i've tried setting the background black before blurring, but the error still occurs,  plus i want to not clear the buffer to have acumative effect

the strange thing is it only sometimes happenes
