Blank page on startup

Hello, I've just tried to install gnvim but cannot start it, i'v just a blank window. The error on terminal is :

thread 'main' panicked at 'failed to decode redraw notification: Syntax("error while decoding value: invalid length 7, expected struct WinViewport with 8 elements")', ui/src/components/appwindow/imp.rs:78:26 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

with backtrace=1 :

thread 'main' panicked at 'failed to decode redraw notification: Syntax("error while decoding value: invalid length 7, expected struct WinViewport with 8 elements")', ui/src/components/appwindow/imp.rs:78:26 stack backtrace: 0: rust_begin_unwind at /rustc/84c898d65adf2f39a5a98507f1fe0ce10a2b8dbc/library/std/src/panicking.rs:579:5 1: core::panicking::panic_fmt at /rustc/84c898d65adf2f39a5a98507f1fe0ce10a2b8dbc/library/core/src/panicking.rs:64:14 2: core::result::unwrap_failed at /rustc/84c898d65adf2f39a5a98507f1fe0ce10a2b8dbc/library/core/src/result.rs:1750:5 3: gnvim::components::appwindow::imp::AppWindow::io_loop::{{closure}} 4: glib::main_context_futures::::spawn_local_with_priority::{{closure}} 5: glib::main_context_futures::TaskSource::dispatch 6: g_main_context_dispatch 7: 8: g_main_context_iteration 9: g_application_run 10: gnvim::main note: Some details are omitted, run with RUST_BACKTRACE=full for a verbose backtrace.

I did the tests and have an error :

Running tests/nvim.rs (target/debug/deps/nvim-ce971b82526dea01) running 2 tests test smoke_test ... ok test smoke_test_ui_attach ... FAILED

failures:

error: test failed, to rerun pass -p nvim-rs --test nvim

`

I precise that i'm under archlinux. I compiled either stable and master version. All gtk4 libraries are installed.

Thanks

The win_viewport event failure hints that you're running nvim version lower than 0.9. Gnvim requires nvim 0.9.

indeed I had nvim 0.8.3, I didn't updated my system. It works well now, thank you very much
