I use KDE with 2 identicals externals monitors, the "secondary" monitor (right) often not start with the good configuration (configured panel + wallpaper). It starts without any panel and another wallpaper. STEPS TO REPRODUCE 1. 2 monitors (mine are identicals with a thinkpad ultra dock) 2. add a panel in the secondary and change the wallpaper for example. OBSERVED RESULT ~50% of times, after plasma starts, the secondary monitor doesn't contains the panel and the wallpaper is wrong. I guest the restored setup is an old. EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora 33 KDE (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2
