With Arch Linux the application doesn't work

[ogarcia]

Describe the bug

On an updated Arch Linux installation the application simply does not work. It starts but the screen goes blank and you can't do anything else.

I have found that this happens both with the precompiled 2.2.6 binary (no matter how it is packaged, be it deb, appimage...) and by downloading the git version and compiling locally.

Reproduction

1. Install Arch Linux or use a virtual image. Upgrade all packages to latest version with pacman -Syu.
2. Install dependencies:

   pacman -S webkit2gtk openssl gtk3 appmenu-gtk-module \
    libappindicator-gtk3 librsvg libvips sqlite gst-plugins-good \
    rust nodejs npm
   

3. Compile git version:

   git clone --recursive https://github.com/cinnyapp/cinny-desktop.git
   cd cinny-desktop/
   cd cinny/
   npm ci
   cd ..
   npm ci
   npm run tauri build
   

   On completion it may give an error to create the AppImage, but it is not necessary because we already have the binary in cinny-desktop/src-tauri/target/release.
4. Run it.

Expected behavior

Just get it to work. But as I said before, it starts but the window remains blank.

Platform and versions

1. OS: Arch Linux
2. Cinny version: 2.2.6 and git
3. Matrix homeserver: n/a
4. Downloaded from: Git and GitHub release

Cannot reproduce on a fresh installation of EndeavourOS (i.e. Arch). Precompiled AppImage also works.

@meequrox EndeavourOS is not Arch Linux, it is a derivative of Arch Linux and does not behave the same.

My advice is to try a virtual image of Arch Linux as I mentioned in the opening of this issue.

EndeavourOS is not Arch Linux, it is a derivative of Arch Linux and does not behave the same.

It's literally Arch + Calamares + some eos tools. I was too lazy to manually install Arch, so I chose that :)

On virtual Arch Linux image the application also works:

@meequrox What is your graphics card? It seems to me that the bug has to do with graphics acceleration on NVIDIA cards (with DRI enabled and original/privative drivers).

I have found the related bug causing the problem, this is it: tauri-apps/tauri#7927

An workaround to make it work until the root problem is fixed is to run cinny in the following way:

WEBKIT_DISABLE_COMPOSITING_MODE=1 cinny

@ogarcia I use AMD GPU with Xorg

@meequrox confirmed, it is a problem with NVIDIA acceleration: https://bugs.webkit.org/show_bug.cgi?id=180739
