ProjectLibre has a major new release coming out this week. Yes — upgrading ProjectLibre backend and Java 21 can significantly improve display issues, especially on 4K displays and high-DPI screens.
Here’s why:
✅ Improvements from Upgrading to Java 21
🖥️ 1. Better HiDPI/4K Scaling Support
some previous Java had poor native support for high-resolution displays, often resulting in:
Blurry UI
Tiny text and icons
Misaligned layouts
Java 9+ introduced HiDPI scaling improvements — Java 21 continues this with refined behavior for:
Windows scaling
macOS Retina displays
Linux HiDPI environments
🧱 2. Modern Graphics Rendering
Java 21 has better support for GPU-accelerated rendering and modern font rendering, reducing lag and improving clarity.
Consistent scaling across different platforms and DPIs.
💡 Summary
Yes — the upgrade to Java 21 will very likely:
Make ProjectLibre sharper and more usable on your 4K displays
Improve text and layout scaling
Provide a more modern visual experience
