Created attachment 155789 [details] this is the video where i show the bug SUMMARY *** When you add multiple panels on the top (maybe everywhere, I haven't tested it), it leaves a space equal to the sum of the panel heights (for me, 75px, three panels and 25px each one). It doesn't affect normal apps, but it does affect Yakuake, Krunner, etc., and also affects files on the desktop (you can't put any files in this 75px area) as shown in the video below *** STEPS TO REPRODUCE 1. add new panel in the top 2. align it to right (as i tested, there is no matter where the panel is aligned, the number and height is matter) 3. change panel width (to allow you to add new panel) 4. add new panel also in the top 5. align it to left 6. change panel width (optionally) 7. you can add new panel also OBSERVED RESULT (i have 3 panels, and set 25px height for each panel) krunner, yakuake start 75px below from the screen EXPECTED RESULT krunner,yakuake start 25px below from the screen SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch linux (available in About System) KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.102.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION its tested only in wayland, also its doesnt affect apps in fullscreen also sorry for my bad english
