The problem has persisted for years
This feature hasn’t existed for years, it’s quite new.
This has absolutely nothing to do with GTK or system trays, and it is in no way or form specific to KDE Plasma or a bug in it. It’s an Xwayland feature that was poorly thought out and that’s challenging to work around.
kde on wayland issue is making it pop up over and over again
Unfortunately it’s an Xwayland issue. It doesn’t remember the permission, and it also doesn’t give the desktop any information to work around it. Because of how portals work, the desktop doesn’t even know the request is coming from Xwayland :/
It’s not a shortcut configured by us, but a thing Xorg does specifically. Be grateful it doesn’t require editing Xorg configs…
No, that’s completely wrong. Like I said, Xwayland doesn’t remember the permission, which xdg-desktop-portal-kde would very much support.
You get the exact same prompts every single time on Gnome too.
