DGA only handles master devices but it does intercept slave device events as well (since the event handlers are per event type, not per device). The DGA code must thus call into UpdateDeviceState to reset the button/key state on the slave device before it discards the remainder of the event. Test case: - Passive GrabModeSync on VCP - Press button - Enable DGA after ButtonPress - AllowEvents(SyncPointer) - Release button The button release is handled by DGAProcessPointerEvent but the device state is never updated, so the slave ends up with the button permanently down. And since the master's button state is the union of the slave states, the master has the button permanently down.
