In my java external application I am drawing into JitterMatrix using jit.gl.sketch then display the JitterMatrix in a window. My order of operations are;

(1)Draw some stuff using sketch to JitterMatrix

(3)Draw more stuff using sketch to JitterMatrix

Logically I expected that (2) will change what I have drawn in (1) , then on top of the changes (3) will appear without any affect from (2)

But what I see is (3) is completely missing ????? only (1) and (2) working ...

But If I comment out (2) I can see everything is drawn properly

Can anyone explain what is happening here ???????????

(1)Draw some stuff using sketch to JitterMatrix
(2)Change the pixels in JitterMatrix
(3)Draw more stuff using sketch to JitterMatrix
(4) send the JitterMatrix to window

Logically I expected that (2) will change what I have drawn in (1) , then on top of the changes (3) will appear without any affect from (2)
But what I see is (3) is completely missing ????? only (1) and (2) working ...
