Had the same issue on my MacOS 15. I resolved it by manually editing Info.plist. It is not ideal (a bit blurry on Retina display but fine on larger external displays).

### Steps to Manually Edit `Info.plist`:

1. **Locate the GanttProject Application:**

- Open Finder.
- Navigate to where GanttProject is installed (e.g., in the `/Applications` folder).

1. **Show Package Contents:**

- Right-click on `GanttProject.app` and select **Show Package Contents**.
- Go to the `Contents` folder.

1. **Open the `Info.plist` File:**

- Inside the `Contents` folder, find the `Info.plist` file.
- Open it with a text editor (TextEdit or Xcode).

1. **Change the Value:**

- Locate this line:

```auto
<key>NSHighResolutionCapable</key>
  <string>true</string>

```

- Replace both lines with:

```auto
<key>NSHighResolutionCapable</key>
<false/>

```

1. **Save the File:**

- Save your changes and close the file.

1. **Restart GanttProject:**

- Relaunch the app and check if the issue is resolved.

Note that this edit might have to be redone if you update the app.
