ProjectLibre on 4K-monitors

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
