Comment 2 Roke Julian Lockhart Beedell 2025-05-14 15:18:54 UTC 
(In reply to Roke Julian Lockhart Beedell from comment #0)

I have now had this reproduce in a more visible manner. I installed KInfoCenter, and used the copy button to add the relevant information into my clipboard. This caused DrKonqi to appear. However, its notification's buttons did nothing when clicked, and despite the icon remaining in the status bar for a few minutes, the notification was inaccessible from the shell.

`bt full` looks the same in a few places, so I shan't attach it for the sake of brevity.
Comment 3 Roke Julian Lockhart Beedell 2025-07-08 16:38:09 UTC 
I can reproduce on PMOS 25.06 too:
