Bug Description

Clients get occlusion/visibility events when visibility isn't actually changing.

Every time I rotate the screen (Ctrl+Alt+arrow) or change display mode (Ctrl+Alt+=/-), mir_demo_client_egltriangle reports that visibility has changed:

60 FPS
59 FPS
60 FPS
Surface occluded
Surface exposed
45 FPS
56 FPS
Surface occluded
Surface exposed
42 FPS
60 FPS
60 FPS
60 FPS

But actually the client remains visible on every frame, and should be.

Actually, this is possibly not fixed at all. It might be masked by bug 1359487.
