While the PR description explains the reason for this change, it would be beneficial to add a comment here in the code. This example serves as a reference for users, and a comment would clarify why this setting is necessary for AWT canvas integration on platforms like Wayland.

Suggested change
settings.setX11PlatformPreferred(true);
// On Linux with Wayland, AWT/Swing requires an X11 context.
// This forces the jME context to use X11 (via GLX) to be compatible.
settings.setX11PlatformPreferred(true);
