Bug Description

Bypass causes non-bypassed surfaces to become unreachable.

1. mir_demo_server_shell --compositor-report=log
2. mir_demo_client_eglplasma
3. mir_demo_client_flicker

Expected: Flicker to appear on top, to be able to Alt+Tab between the surfaces and move plasma with Alt+drag
Observed: Alt+Tab and Alt+drag both do nothing. Flicker never becomes visible at least for the first few tries. Eventually you can Alt+Tab to plasma enough times to then be able to drag it, disabling bypass and thus making switching to flicker possible.

Alternate test case:

1. mir_demo_server_basic
2. mir_demo_client_eglplasma
3. mir_demo_client_flicker

Expected: Flicker to appear on top
Observed: Flicker never appears, unless you "env MIR_BYPASS=0" on the server.

Come to think of it, this explains why some users could never run demo clients on top of XMir. Not sure if we ever had a bug logged for that, but should be fixed now anyway.
