In the typical pattern in games of "hide cursor, grab with a confineTo, warp constantly the pointer to the middle of the window" the last warping step is actually rather optional. Some games may choose to just set up a grab with confineTo argument, and trust that they'll get correct relative X/Y axis values despite the hidden cursor hitting the confinement window edge. To cater for these cases, lock the pointer whenever there is a pointer confinement and the cursor is hidden. This ensures the pointer position is in sync with the compositor's when it's next shown again, and more importantly resorts to the relative pointer for event delivery.

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.
