SUMMARY It seems like on KDE Plasma 5.27.2 running Wayland, lattedock does not know which screen is primary. This results in the panels/dock being shown on my laptop's monitor, despite my external monitor being set as the primary display in the display configurations. STEPS TO REPRODUCE 1. Set up lattedock to show on primary display 2. Run wayland 3. It shows on the wrong screen SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8
I'm experiencing the same problem. It's a new problem for me. I've been happily using lattedock with multiple screens for about a year now without issue, so I suspect it's a recent update that's borked things. I noticed that in the "Display Configuration" options now, you choose the order of priority for your screens rather than just setting one as the primary. I wonder if this change has subtly broken something?
Forgot to add: KDE Plasma version: 5.27.3 KDE Frameworks version: 5.104.0 Qt version: 5.15.8
