(In reply to tuefue from comment #0) > b) Messages appear in console: "This plugin supports grabbing the mouse only > for popup windows" I think *that*'s merely due to LO using docks, because I can reproduce that message on kwin-6.2.5-1.fc41.x86_64's Wayland session in a basic PyQt6 application with `QDockWidgets`, and it appears in https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-22-04-jammy-jellyfish/desktop-environment-support/671309-first-wayland-failure#post671309:~:text=This%20plugin%20supports%20grabbing%20the%20mouse%20only%20for%20popup%20windows, which is about Kate, which itself uses `QDockWidget`s. There seems to be a topic about it at https://forum.lazarus.freepascal.org/index.php?topic=64141.0, but IDK what most of what they've said there means.
