When logging into a Wayland session the taskbar worked just fine starting out, but when pinning multiple apps to the taskbar, the task bar started to behave weirdly, especially when swapping multiple icons with each other.
For me, it was still possible to swap the icons, as long as the task bar is clicked after each time an app is dragged along multiple other apps.
Also the apps in the Application launcher no longer showed a function to unpin apps, but unpinning apps still worked fine through clicking the task bar.
Note that this happened some time ago and might no longer be that urgent and it might already be fixed, but I wanted to raise awareness of this issue regardless.
Thank you for taking time!
