Graphics 2.0 crash with 2014.2432

Hello, I am trying to create new effect by combining existing ones and Corona Simulator crashes.

Here is my code.

graphics.defineEffect({ language = "glsl", category = "filter", name = "myEffect", graph = { gray = { effect = "filter.grayscale", input1 = "paint1" }, --final = { effect = "filter.contrast", input1 = "gray" }, }, output = "gray" }); local rect = display.newRect(100, 100, 100, 100); rect:setFillColor(1, 0, 0); rect.fill.effect = "filter.myEffect";

Also question about arguments for filter. How can I specify arguments for filter contrast in this sample?

Thank you
