Created attachment 114114 [details] the bug (see short attachment video) This happens when you hover on a dock after logging into kde (with the dock in autostart). I've then tried to reopen it but the bug didn't happen again. Only on initial login, every time. Plasma 5.13.3 Qt 5.11.1 latte-dock 0.8.1 (master) Tell me if you need additional info/testing.
