Describe the bug

When launching with the SCRCPY_ICON_PATH environment variable set, the default icon is used instead.

Terminal output indicates the environment variable is being read, but the default icon is still used.

Workaround (kind of)

Replacing the image at /usr/local/share/icons/hicolor/256x256/apps/scrcpy.png with my own image, then logging out and back in, results in the new icon being used. However, my goal was to have a separate icon for separate instances of scrcpy (ex. one for Textra, one for Gmail, etc).

[rom1v]

If you run scrcpy --no-video, is your icon used for the window content? If so, I guess the window icon is cached by your window manager.

[nhobson99]

Looks like yes, it is read and used. Is there a way to turn off the icon caching? I'm on Gnome 42.9 if that matters. I just want the Textra window to look like Textra in my taskbar.
