Off screen display windows placement when using P3D or P2D

[dkemp]

When using P2D or P3d my display window appears partially off-screen in the upper left – this even happens when using fullscreen or present mode, which do not actually fill the whole screen anymore. I have a feeling this has something to do with my windows display scaling (currently at 225% for my small laptop sceen), but I am not sure how to fix it.
There is no issues when using the default renderer so not sure what to do. Is this a bug, or something I need to adjust in my display settings or something?

Hello @dkemp ,

Try this and change x and y as required:

void setup()
  {
  size(300, 300, P2D);
  int x = 600;
  int y = 600;
  surface.setLocation(x, y);
  }
  
void draw()
  {
  }

I know the scaling affects my sketch window size:

Launcher for Multi-Renderer PApplets

Hello folks! My exploration of a launcher for PApplets with different renderers. This was used primarily for testing Windows scaling on my W10 system and how it affects the sketch window. Code: /** * Launcher for Multi-Renderer PApplets * * Author: glv * Date: 2025-07-07 * * Description: * Launches four separate Processing sketches (PApplets) using different renderers: * - JAVA2D * - P2D * - P3D * - FX2D * * Each renderer runs in its own thread, with readiness flags for commu…

@glv

surface.setLocation(x, y);

Thanks that really helps a lot and solves the issue when running the sketch normally; however, I’m still getting some weird behaviors when using fullScreen(P3D); or running the sketch in “present” mode.

Also wondering if this is a bug in the latest version as none of this occurred in earlier (4.3 and earlier) versions of processing.
