'Shadow' under floating panel since update to 6.1

Just wondering if anyone can help here, or confirm this is an issue.

I just noticed today that my lower floating panel has what I can only describe as a shadow under the panel - It wasn’t present under KDE Neon 6.0.x and only became apparent after the update to KDE Neon 6.1.

Edit: the issue only seems to be present on my lower floating panel, the upper fixed panel appears to be fine. Running the Breeze Dark theme and X11. EDIT: The same issue is present under Wayland.

See the attached images for reference:


I’ve got a pretty vanilla install here, someone else has to be experiencing this issue?

This has been already fixed. You will get the fix with the next update.
