### Describe the Bug

After updating from 2026.131.140325 to 2026.203.160441, sunshine cannot be used directly for streaming like before (it should be, because previously on my GNOME desktop, this icon did not appear below). However, if I enter desktop and start sunshine from the terminal, there is no problem.
