On Wayland, when transparency and blur are enabled in Konsole's active color scheme, its session menu leaves a shadow box for a short moment after it has been dismissed.
STEPS TO REPRODUCE
1. Log into Plasma (Wayland)
2. Open-up Konsole
3. Enable blur and set some level of transparency for the current color scheme, e.g. 20%
4. Right click on Konsole's background to get the session menu and then dismiss it, pressing ESC or clicking anywhere else.
The session menu leaves a shadow box behind where it was, which remains for a short moment.
The session menu leaving no shadow boxes after dismissing it.
