>From the XF86Config-4 manpage, about the ServerFlags section:
Option "AllowDeactivateGrabs" "boolean"
This option enables the use of the Ctrl+Alt+Keypad‐Divide key
sequence to deactivate any active keyboard and mouse grabs.
Default: off.
[...]
Note that the options AllowDeactivateGrabs and AllowClosedown‐
Grabs will allow users to remove the grab used by screen
saver/locker programs. An API was written to such cases. If you
enable this option, make sure your screen saver/locker is
updated.

Strictly speaking, it may be an X server bug that the grab persists when
the client goes away.
