Are you running Wayland or X11?
I run it on Fedora with Wayland and have never seen this error before.
I might have to create a unique Arch package for it...
Did you try building it from source?

I can confirm this issue on Arch Linux with the latest AppImage (also tested with 0.3.6). Same behavior: white screen + immediate abort with EGL_BAD_PARAMETER.

I ran a full set of diagnostics to narrow it down — this looks like an AppImage + Tauri/WebKitGTK + EGL runtime incompatibility on Arch rather than a broken local GL stack.

Environment:

• OS: Arch Linux (fully up to date)
• Session: reproduced under both Wayland and X11
• GPU stack: Mesa OK
• EGL system stack: working (eglinfo runs fine)
• Shell: fish (also reproduced via bash)

Baseline error:

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

Tests performed

Tried forcing X11 backend:

env GDK_BACKEND=x11 ./RustySEO_xxx.AppImage
env QT_QPA_PLATFORM=xcb ./RustySEO_xxx.AppImage

→ same EGL error

Forced software GL:

env LIBGL_ALWAYS_SOFTWARE=1 ./RustySEO_xxx.AppImage

→ same EGL error

GL debug:

env LIBGL_DEBUG=verbose ./RustySEO_xxx.AppImage

→ no additional useful signal, still fails at EGL init.

Extracted AppImage and ran directly:

./RustySEO_xxx.AppImage --appimage-extract
cd squashfs-root
./AppRun

→ same EGL error

Forced system libraries:

env LD_LIBRARY_PATH=/usr/lib ./AppRun

→ same EGL error

Tried wgpu / backend overrides:

env WGPU_BACKEND=gl ./AppRun
env WINIT_UNIX_BACKEND=x11 ./AppRun

→ same EGL error

EGL on host is working:

eglinfo

prints normal platform/extensions info without crashing.

Additional hint

When running the extracted build, I see:

WARN tauri_utils: `APPDIR` or `APPIMAGE` environment variable found but this application was not detected as an AppImage

Since this is a Tauri app, the failing component is very likely the embedded WebKitGTK/EGL path inside the AppImage runtime. Arch’s rolling Mesa/libdrm/libgbm stack may be ABI-incompatible with the bundled libraries.

Notably:

• EGL works system-wide
• GL software fallback does not help
• X11 vs Wayland does not change outcome
• Failure happens before UI render → EGL display creation stage

Hope this helps narrow it down.

I'm going to try the cli version

Might need to open an issue with Tauri.
I am not sure I can work around this as it seems to be related to the webview interaction with Arch.
If you compile it from scratch do you still get the same errors?

The TUI/CLI version does not involve Tauri as it is using Ratatui instead, below that its pure rust.
I don't expect any issues there.
But please let me know if you find any.

Cheers for the feedback.
