How to open maximized window with windows taskbar. I’m using the newest version of processing, and any version of` size(displayWidth, displayHeight); surface.setResizable(true); surface.setLocation(0, 0);` doesn’t work.

Use command fullSize - see reference
(fullScreen())

Hi @Rafsing
I think the main Processing 3.0 issue here is you can’ t use variables as arguments for `size()` on `setup()` anymore. Have a look at: [https://processing.org/reference/settings\_.html](https://processing.org/reference/settings_.html)
But then, using `surface’ for everything it works for me:
```auto
void setup() {
surface.setResizable(true);
surface.setSize(displayWidth, displayHeight) ;
surface.setLocation(0, 0);
}
void draw() {
background(255, 0, 0);
ellipse(width/2, height/2, 100, 50);
}
```

Use the `FX2D` renderer mode and the maximise button becomes available.

I found this discussion, but so far it shows that there is no solution and must be done manually.

I’m on Linux (Xubuntu, Ubuntu + XFCE)
@micycle has a good point, different renderers have different surface instances
(P2D, P3D, FX2D and the default renderer could act differently)
