Not wanting to discredit your experience, but that sounds very strange.

This sounds to me like leaking resources from the binding. Which binding did you use and how did you manage it's lifetime?

I remember we used https://github.com/getlantern/systray at some point along with some interaction with fyne.io. That said, I do not remember how we managed the lifetime but we did test it thoroughly before deploying to our initial beta users (or so we thought :P). The GC behavior started to happen whenever the app was in the background, which it was supposed to be for the majority of the time.
