This is a blur effect, which is drawn super slow at 1fps, the surprise surprise part is once i go to this line
"imageData[index] = value;" and set it to like RED or whatever, frames are going back to 40, so I think there's something I'm missing here, but i have no idea what it is.

Oh and it also crashes

It seems to be doing some sort of addittive part to it, the image for the few frames is visible before it crashes while bluring properly it seems to be doing some sort of addittive part, here's a screenshot before it crashes
