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

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

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

Do you use

    window.graphics.endDraw();

?

Can you post an mcve?

Yes, please do!

For example:

beginRecord() with a PGraphics2D interferes with the background of the main PApplet · Issue #3180 · processing/processing · GitHub

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.
