Describe the bug
When using the libappindicator-gtk3 library for tray icons, the icons don't appear when auto starting solaar with the window=hide flag in Wayland. I have removed the package and installed libayatana-appindicator instead which works, but the question remains as to why it's only seemingly affecting Arch Linux on the distributions tested. It fails to execute the program when logged into a new session in the DE. I note that some distros have deprivcated the libappindicator-gtk3 package in favour of libayatana-appindicator, so perhaps this is the way forward regarding what dependencies are shipped and used in the repos for Solaar?

To Reproduce
Steps to reproduce the behavior:

1. Install libappindicator-gtk3

2. Reboot/restart DE and check journalctl -b | grep solaar

3. Scroll down to arch solaar[986]: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed

4. See error

The tray icon seems to show up when running it manually either via terminal or application menu. Those GTK errors mentioned above appear on boot/login.

Nothing seems to pop out, here's the output of solaar -dd:

In docs/installation.md there is the comment that Solaar installation in KDE you need to have ayatanaappindicator3 installed. The wording there is confusing so improving it would be useful. What exactly did you install or remove? Do you have any suggestions on what this should read?

[pfps]

It may be that running Solaar at startup needs to be done carefully so that required resources are available when Solaar starts. How do you arrange for Solaar to be run at startup?

[pfps]

The flag --window=hide just turns of showing the main window at startup. Running Solaar with no flags at startup should work the same, except that the Solaar main window should show up.

I removed libappindicator-gtk3 and installed libayatana-appindicator prior to the discussion and the tray icons appeared on autostart. As per your instructions, I reinstalled libappindicator-gtk3 and removed the other package for debug purposes.

I have a .desktop file at /etc/xdg/autostart/solaar.desktop. It runs fine under Ayatana AppIndicators, it fails with a GTK warning on the default libappindicator-gtk library.

I'm updating the installation documentation to say:

Solaar needs a library to interact with the system tray. The library that provides this interaction depends on the distribution and window system. If ayatana appindicator is available then it is best to have this library installed, e.g., by installing libayatana-appindicator or gir1.2-ayatanaappindicator3-0.1 or similar, depending on distribution. Otherwise appindicator can sometimes be used, e.g., by installing libappindicator-gtk3 or gir1.2-appindicator3-0.1 or similar, depending on distribution.

Does this match your understanding of what is required?

Looks clear and concise to me. It will save everyone the hassle trying to troubleshoot the tray icons not appearing without the additional libraries installed when using Wayland.
