Comment 11 for bug 1967964

I have the package libayatana-appindicator3-1, a lot of apps use it without issues.

I found a post saying that Radiotray had the same issue, and I use Radiotray-ng.
I even had an issue with the appindicator 1 year ago here : https://github.com/ebruck/radiotray-ng/issues/165
So I tried to start it from the cli, it output the same error. I tried to start Radiotray-ng from the Alacritty terminal or Xfce4-terminal and I have the same error in the output.

It's not related to xfce4-terminal, it just had the same issue some years ago.
If I start xfce4-terminal (with "xfce4-terminal --drop-down", to use the systray icon) from Alacrtty, there is no error.
Apparently they fixed it here :
https://git.xfce.org/apps/xfce4-terminal/commit/?id=eff5e2db3dff7e586193e95156da24f2acf33eeb

Also there is this issue for SystemTray where they found a correction too : https://github.com/dorkbox/SystemTray/issues/19

Apparently everything is related to GDK, the systray and maybe appindicator.
