SUMMARY
Hi and thank you for developing KWin!
Please refer to the issue in KDE's gitlab, the link brings directly to the error message
https://invent.kde.org/teams/plasma-mobile/issues/-/issues/156#note_494689
My usecase comprises Pinephone as HW, while OS is Debian testing plus Plasma mobile from https://jbb.ghsq.ga/debian-pm/ but this happens on different devices and OSes, as reported in the original issue.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.25.4
KDE Frameworks Version: 5.97
Qt Version: 5.15.4

I know you're being sent back and forth, but this isn't a kwin bug.

The logs are saying kwin noticed the client did something wrong (calling get_registry with an object that's not a display) and then the client is correctly given an error back.

Jul 28 21:43:11 manjaro-arm kwin_wayland_wrapper[4319]: wl_display@1: error 1: invalid arguments for wl_display@1.get_registry
Jul 28 21:43:11 manjaro-arm kscreenlocker_greet[4319]: The Wayland connection experienced a fatal error: Invalid argument

I've replied on that original ticket asking for more info. There must be something more interesting happening first.
