STEPS TO REPRODUCE 1. Start with default latte-dock config (~/.config and ~/.cache emptied). 2. Run Kate. 3. Its icon appears in Latte. 4. Click on the Clock/Calendar widget and then click it again to make the calendar popup window disappear. 5. Move the mouse cursor a little. OBSERVED RESULT The Kate icon disappears and shortly reappears as if it was just started. EXPECTED RESULT The Kate icon doesn't disappear at all. SOFTWARE/OS VERSIONS Linux/KDE Plasma: ArchLinux and FreeBSD KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.104 (5.102 on FreeBSD) Qt Version: 5.15.8 KDE Patches.
Screencast demonstrating the problem: https://arrowd.name/latte-dock-bug.mp4 The problem can be observed on 0:04 and 0:20 after clicking the rightmost Calendar icon.
This seems related to the issue I'm having where unpinned, running apps disappear and then reappear sometimes when the dock is shown after auto-hide.
