--- Comment #31 from Nate Graham <nate at kde.org> ---
Git commit fc4981c4ec73cd2d1f15dbacc13fc8dc4d047a18 by Nate Graham.
Committed on 11/07/2025 at 17:06.
Pushed by ngraham into branch 'Plasma/6.4'.

lockscreen: prevent immediate prompting for the password

As of Qt 6.8.2, the fix for QTBUG-127122 causes a positionChanged event
to be emitted when handling QEvent::HoverEnter.

The lockscreen creates a full screen MouseArea on every connected
screen, one of which will cover the current position of the mouse
pointer. This causes QEvent::HoverEnter and then the positionChanged
event to be raised immediately. The mouse position did not change.
Ignore the spurious (first) positionChanged event, show the password UI
as usual in response to further events.
