On a Wayland session, the plasma panel has no shadow (the nice line at the top of the panel, see the X11 screenshot as I can't make a screenshot on Wayland). Reproducible: Always Steps to Reproduce: 1. open a Wayland session with a Plasma desktop that has a panel. 2. 3. Actual Results: The panel has no shadow like it has on X11.
Created attachment 101113 [details] This is the shadow the panel is supposed to have on Wayland (X11 screenshot).
Still present in Plasma 5.8.1 (KDE Neon).

I'm reopening this bug, because on Plasma 5.10, at session opening, the Plasma panel does not have shadow (but other plasma elements do : K menu has shadow, systray menu has shadow...) ; I'm using Breeze Dark : if I change the Plasma theme to something else and then switches back to Breeze Dar, the shadow is there again.
This bug no longer appears for me in: Distribution: KDE neon Developer Edition Unstable Branches KDE Plasma Version: 5.10.90 KDE Frameworks Version: 5.37.0 Qt Version: 5.9.1 Kernel Version: 4.10.0-32-generic OS Type: 64-bit
Thanks for the feedback. I mark as fixed, if you see it again please reopen.
