SUMMARY Running a custom window manager on X11 (following Archlinux Wiki systemd procedure): a panel never hides itself, neither in autohide mode nor in dodge windows. STEPS TO REPRODUCE 1. mask/stop plasma-kwin_x11 service 2. create/enable/start a custom user service to launch a window manager 3. set dock to autohide OBSERVED RESULT The dock never hides itself. EXPECTED RESULT The dock should be able to hide itself (and to dodge windows when using another window manager) SOFTWARE/OS VERSIONS Linux/KDE Plasma: Archlinux (available in About System) KDE Plasma Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION It works in the same setup when running kwin. It also works when running kwin with a custom composite manager (tested with compfy and picom) where the dock fades away appropriately. Not-working when using another simple window manager instead (tested with a custom EWMH compatible dwm and a default up-to-date icewm). Latte-dock, in plasma 5, did not have this issue (dodge windows was working fine). Cannot say for pure plasma 5 dock in this setup (never tested).
