why would i get `RuntimeException: Too many pushFramebuffer calls` when calling

```auto
    window.graphics = createGraphics(window.width, window.height, type);
    window.graphics.beginDraw();

```

```auto

is this in setup() or in draw()?

Do you use

```auto
    window.graphics.endDraw();

```

?

Can you post an mcve?

For example:

> This should show a white background with a black diagonal line. But the backgrou…nd stays the default gray. If you remove the P2D argument to createGraphics, it works OK (then the default Java2D renderer is used).

> Don’t call `createGraphics()` inside `draw()` . That example is creating new OpenGL drawing contexts at 60 frames a second. That’s not a Processing problem, you’re going to crash your machine no matter what language you use.
