Linux AppImage (v0.2.6) aborts with "EGL_BAD_PARAMETER" / renders black or blank white window on newer Mesa hosts (bundled libwayland/libxkbcommon/libxcb conflict)

[ket000]

Describe the bug

netscli-gui-linux-x86_64.AppImage (v0.2.6) fails to start correctly on a
host with a newer Mesa than the AppImage was built against. Depending on the
GPU/compositor, this shows up as one of two related failures:

1. Running the AppImage as-is aborts immediately with:

   Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...

2. After removing the conflicting bundled libraries (see below), the app
   window opens but renders as a solid black or blank white window with no
   UI content — the WebKitGTK compositor fails to paint anything.

Root cause

The AppImage (built via linuxdeploy + the gtk plugin) bundles its own copies
of the display stack under usr/lib:

libwayland-client.so.0   libwayland-cursor.so.0
libwayland-egl.so.1      libwayland-server.so.0
libxkbcommon.so.0
libxcb-render.so.0       libxcb-shm.so.0
libXau.so.6              libXdmcp.so.6

AppRun.wrapped sets LD_LIBRARY_PATH so these bundled (older) libraries are
loaded ahead of the host's. On a host with a newer Mesa (e.g. CachyOS rolling,
Mesa 26.2.2), eglGetDisplay/eglGetPlatformDisplay fails against the stale
bundled libwayland-client, producing the EGL_BAD_PARAMETER abort.

This matches a known linuxdeploy/Tauri bundler issue:
tauri-apps/tauri#15976
and a duplicate: tauri-apps/tauri#15665

Separately, even after fixing the EGL abort, WebKitGTK's hardware compositing
path can fail silently and produce a black or blank white window (no error on
stderr) — seen on a VMware VM using the vmwgfx driver where 3D acceleration
is only partially/software-supported.

Steps to reproduce

1. Download netscli-gui-linux-x86_64.AppImage from the v0.2.6 release.
2. chmod +x and run it on a distro with a newer Mesa (e.g. CachyOS,
   Fedora 44+, Arch) — observe the EGL_BAD_PARAMETER abort with no window.
3. Apply the library-removal workaround below — the window now opens but is
   solid black or blank white with no rendered content.

Workaround (confirmed working)

./netscli-gui-linux-x86_64.AppImage --appimage-extract
rm squashfs-root/usr/lib/{libwayland-client.so.0,libwayland-cursor.so.0,libwayland-egl.so.1,libwayland-server.so.0,libxkbcommon.so.0,libxcb-render.so.0,libxcb-shm.so.0,libXau.so.6,libXdmcp.so.6}
