@Duha, previously, I was using my FW16 (laptop). On my desktop, although the SIGSEGV in QtWayland::wl_seat::object reproduced 1 of the 6 times I invoked /usr/libexec/kscreenlocker_greet --testing, [1] it works otherwise!

Heck, with noborderrule=2 imported from a .kwinrules via kcm_kwinrules (on XOrg 11), [2] I can even resize kscreenlocker for a good screenshot:
| Unfocused | Focused |

| This was easier to capture, since I don’t have to time it, like I would under Wayland. |
