Created attachment 159112 [details] Recording of taskbar icon previews disappearing and moving incorrectly. SUMMARY When I start a Plasma Wayland session, hover an open app in the task manager, and move my mouse to another open app, the preview is slow to move (closes and reopens), and the new one is sometimes positioned incorrectly vertically. STEPS TO REPRODUCE 1. Log in to Plasma (Wayland). 2. Open some apps. 3. Move the mouse around between the app icons on the panel. OBSERVED RESULT The app name tooltips or window previews disappear and appear, sometimes move *then* disappear, and show up at the wrong vertical position. EXPECTED RESULT The tooltips remain open when you move the mouse between apps, like in Plasma X11. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.15.9 Kernel Version: 6.3.1-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 5600X 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 570 Series Manufacturer: Gigabyte Technology Co., Ltd.

I experienced the bug on Wayland dual monitors, and it continues after switching to single monitor, but I did not try logging out and in again.
