SUMMARY When using the global menu widget alongside the icons only task manager widget in the same panel separated by a spacer, changing the focus to an app makes the icons in the task manager resize according to the length of the menu options (smaller if the menu options are longer and vice versa) STEPS TO REPRODUCE 1. create a fixed-size panel 2. add global menu widget on one side, icons-only task manager on the other, and a flexible sized spacer in between them 3. change the focus between different apps OBSERVED RESULT The icons in the icons-only task manager resize EXPECTED RESULT The icons should stay the same size SOFTWARE/OS VERSIONS Linux: Void Linux w/ kernel 5.10.18_1 KDE Plasma Version: 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Using default KDE panel, have not tested with latte panel

This should work now in Plasma 5.27 if you configure both the Global Menu and Task Manager widgets to not fill empty space. You generally need to use this setting in a widget when you put flexible spacers around it.
