Pointer-emulated touch events should only be delivered to the client that owns the sequence even if it's a core client that became the effective owner of the sequency by selecting for pointer press and movement. Currently the emulated events are delivered like this already (see TouchResourceIsOwner() check in DeliverEmulatedMotionEvent()), except in the case of TouchEnd, in which case the generated motion event is still delivered to some client that's not necessarily the owner of the touch sequence. We already know whether a touch sequence that is about to emulate a pointer event has an owner, we just need to check that. This further allows to simplify DeliverEmulatedMotionEvent() as it won't ever be called for non-owned touch events. https://bugs.freedesktop.org/show_bug.cgi?id=60394 Signed-off-by: Povilas Kanapickas <povilas@radix.lt>
X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
