Pekka Paalanen 661de3a6a7 compositor: ignore unmapped sub-surfaces for view_list It looks like that in the great conversion introducing weston_view, one conditional was forgotten from the code that builds the global flat list of views. Sub-surfaces are added to the view list specially, as they are not governed by their presence in a layer's view list, and therefore need an explicit check for mappedness. The bug, missing the explicit check, caused sub-surfaces to enter the global view_list regardless of their state. This lead to the pointer focus picking code processing them, and as the input region defaults to infinite, picking these unmapped surfaces. Clients then get confused about the wl_pointer.enter events with unexpected wl_surface. To trigger this issue, it is enough to just create one additional wl_surface and make it a sub-surface of a main surface that is or gets mapped. Literally, just a wl_subsomcpositor_get_subsurface() call is enough. At some point later, the unmapped sub-surface will get pointer focus, depending on view stacking order. Fix the issue by adding a is_mapped check when building the view_list. Note, that `95ec0f95aa` accidentally also prevents this bug from happening, because it adds a test against the transform.masked_boundingbox in weston_compositor_pick_view().

Weston

Weston is the reference implementation of a Wayland compositor, and a
useful compositor in its own right.  Weston has various backends that
lets it run on Linux kernel modesetting and evdev input as well as
under X11.  Weston ships with a few example clients, from simple
clients that demonstrate certain aspects of the protocol to more
complete clients and a simplistic toolkit.  There is also a quite
capable terminal emulator (weston-terminal) and an toy/example desktop
shell.  Finally, weston also provides integration with the Xorg server
and can pull X clients into the Wayland desktop and act as a X window
manager.

Refer to http://wayland.freedesktop.org/building.html for building
weston and its dependencies.

The test suite can be invoked via `make check`; see
http://wayland.freedesktop.org/testing.html for additional details.
