strobing video

Hello. I am getting some unwanted white frames passed to my jit.window, creating a strobing effect. Everything is fine until begin to pass audio amplitude data to the dimscale of a jit.gl.slab object. Every time the dimesion is changed, the screen flashes white. It seems like it is a buffering problem? Is there any way to avoid this strobe effect?

Thanks.

an example is below
