Can reproduce. Interestingly, [Meta] + [+], [Meta] + [-] and [Meta] + [0] are working.

Hi,
seems like that's intentional for security reasons - https://invent.kde.org/plasma/kwin/-/blob/master/src/input.cpp?ref_type=heads#L455.
The question is does it make sense to make an exception for certain touch pad gestures on lock screen.
Would be great to have some input from KWin team.
