Title:
mirscreencast steals all key events.
Status in Mir:
Triaged
Status in mir package in Ubuntu:

Bug description:
To test:
1) Open up a mir server (i used demo_mir_shell_server)
2) Run a client example (i used demo_mir_client_eglplasma)
3) Run mir screen cast
4) Press 'q' to exit (this is true for the egl examples/demos).
Expected result:
The demo closes.
Actual Result:
No key events happen, and demo stays open.
This seems to be caused by mir screen cast stealing the events. To
confirm this, simply alt+tab in a demo_mir_server_shell which will
bring the demo back into focus. Then a 'q' will exit the progam. (ie.
key events work again).
Testing out:
src/server/shell/default_focus_mechanism.cpp
void msh::DefaultFocusMechanism::set_focus_to();
It looks like its coming from the case when deafult_surface() ==
nullptr. When this happens it clears the input, leaving the demo in
limbo without events!
I can confirm thats the case here as commenting out:
input_targeter->focus_cleared();
Fixes the issue, though im not sure what the real fix for this would
be.
