Program run with 4.3.4 does not run the same with version 4.4.2 and later version

Processing
1

I have been developing a program to analyze and display tracks from GPX files with version 4.3.4. I have been hesitant of taking new version but decided to update to the latest version. I loaded it and was not getting the same output so went to the next release version after 4.3.4, 4.4.2. That has the same problem. I looked at the release notes and could not see anything that would cause the problem. In my opening screen, I display an image which seems to get magnified and other regions of that page do not display correctly, i.e, the status/command line at the bottom. The program is running, that is, the track list was generated after selecting the top left region.

What changed between the releases that would cause this?

There might have been changes in the renderer.
Which renderer?
Is this on Windows?

I’m not very knowledgeable in this area but had problems in the past with FX2D on my Windows system where the Windows scaling (1.25) was applied.

The solution for me was to create a settings function with the below content and remove the size() from setup()

void settings()
{
  // suppress windows scaling; see https://discourse.processing.org/t/windows-ui-scaling-not-respected/45905/5
  // note: System.setProperty("glass.win.uiScale", "1"); needs to be executed in setting, does not seem to have an effect in setup().
  System.setProperty("glass.win.uiScale", "1");
  size(800, 600, FX2D);
  smooth();
}

sterretje,

Thanks for the quick reply. I was in the middle of debugging so it took a bit of time until I got back to checking out your solution. Also, I had to ramp up on installing libraries. When I used it on the latest version, your solution worked like a charm.

Thanks again,

Hello @ndphillips,

What operating system are you using?

This is my working solution for JAVA2D or FX2D with W11 and Processing 4.5.7:

import processing.javafx.*; // If using FX2D otherwise comment out

static 
  {
// Force 1:1 pixel rendering by disabling OS-level UI scaling before the graphics engine loads

  //JAVA2D
  System.setProperty("sun.java2d.uiScale", "1");
  
  //FX2D
  System.setProperty("glass.win.uiScale", "1");
  }

void settings()
{
size(400, 400, JAVA2D);
//size(400, 400, FX2D);
//size(400, 400, P2D);
 }

Modify as required for your preferred renderer.

glv,

thanks for your reply. I am using Windows 11 and now Proceessing 4.5.7. I used the fix suggested by sterretje and it worked. He had not included the import processing.javafs.* but I figured that out. You are suggesting using size(###, ###, JAVA2D) instead of FX2D, is there a reason? FX2D seems to work fine for my use so far.

I am not suggesting which one to use; I only presented options.

Use the renderer that suits your project.

Each renderer has its pros, cons, and quirks. I shared what I learned so that community members are aware of the options available to them.
