Bug description

Hi! I use Cosmic DE and the systray icon does not appear. The log show the error gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed, which seems to be related to the problem.

Steps to reproduce

1. Open the application.
2. Realize that the systray icon does not appear.

Expected behavior

The systray icon should appear.

Here is a log from the application being initialized from the terminal:

Start by reproducing the missing systray icon on CachyOS with the Cosmic desktop, then trace Warpinator's startup and systray initialization while monitoring the reported GTK assertion. The issue provides no source file or test location; done means the icon appears and the GTK-CRITICAL messages no longer occur.
