Xpra: Ticket #1350: gnome shell uses the wrong window icon

We try very hard to ensure that despite the fact that all the windows we forward will be owned by the same xpra process, we set a different group-leader (see "get_group_leader"), we forward the wm-class and the window icon. Unfortunately, gnome-shell will use the first icon we set for all the windows.. Can be tested easily with this standalone app: test_window_icons.py

There could be other window managers that do the wrong thing here, but gnome-shell is the only one I am aware of. Tested: Ubuntu's Unity, MS Windows, KDE, etc.. no problem with any of those. (macos, as usual, does its own thing: only one dock entry.. which we could change when a different application gets focus?)

This may require submitting a patch upstream..

I believe this is no longer the case since #1144, will re-check.

Still a problem. All the window properties are set correctly, but gnome-shell uses something else... sigh.

Fixed in r17250: we create a fake process for each server-side pid, this ensures that gnome-shell does the right thing. We can later use it for handling client-side signals sent to the process owning a window: #1671.

Found some references along the way:
