NeoHtop AppImage fails to launch with `Could not create default EGL display: EGL_BAD_PARAMETER` error on NixOS.

[Aneeqasif]

Steps to Reproduce:

1. chmod +x NeoHtop_1.2.0_x86_64.AppImage
2. Run using any method:
   • Direct: ./NeoHtop_1.2.0_x86_64.AppImage
   • With nixGL: nix run --impure github:nix-community/nixGL -- ./NeoHtop_1.2.0_x86_64.AppImage
   • Software fallback: LIBGL_ALWAYS_SOFTWARE=1 ./NeoHtop_1.2.0_x86_64.AppImage

Expected Behavior:
App should launch (with GPU acceleration or software fallback).

System Info:

• OS: NixOS unstable
• GPU: [Intel ]
• Display: kde/Wayland

Tried Solutions:

• nixGL (all variants)
• Software rendering
• appimage-run --disable-gpu
• All produce same EGL error

Additional Notes:

• Standard htop works fine
