Describe the bug

When installing or building the app in Ubuntu 22.04, I get a blank screen. If I run the app from the terminal, this is the logs I am getting:

warning: `devman` (lib) generated 3 warnings (run `cargo fix --lib -p devman` to apply 2 suggestions)

To Reproduce Steps to reproduce the behavior:

1. Download the .deb package for amd64
2. Install it with sudo dpkg -i

Expected behavior

Hello! Does the workaround mentioned in https://github.com/DioxusLabs/dioxus/issues/1909 work?

@mariotaku I can confirm it works, I changed my .desktop file to add the environment variable and it now works. This is how my .desktop file looks like now for anyone experiencing the same issue:

╰─❯ cat /usr/share/applications/web-os-dev-manager.desktop
[Desktop Entry]
Categories=Development;
Comment=Device/Dev Mode Manager for webOS TV
+Exec=env WEBKIT_DISABLE_COMPOSITING_MODE=1 web-os-dev-manager
-Exec=web-os-dev-manager
Icon=web-os-dev-manager
Name=webOS Dev Manager
Terminal=false
Type=Application

Don't forget to run sudo update-desktop-database to ensure your .desktop icon is updated with the changes immediately.
