Hmm, cannot reproduce.

Do any other pop-ups and widgets exhibit the issue, or just the system tray and notifications?
Comment 3 hexchain 2023-02-21 13:42:37 UTC
Yes, it also happens with other widget popups, such as system monitor sensors. But I have 3 such widgets and only one of them has these corners.

Changing the color scheme or Plasma theme makes these corners disappear for the current session.
Comment 4 hexchain 2023-04-11 13:47:22 UTC
I think it happens more frequently if the panel opacity is set to "Translucent" instead of "Adaptive".
Comment 5 Nate Graham 2024-08-20 00:25:03 UTC
Ah, the Korners bug. It got fixed in Plasma 6.1, IIRC.
