* Task Manager and System Tray widgets are separated by panel spacers
(see attachment 1 [details])


STEPS TO REPRODUCE
1. Create a panel as on the screenshot in the attachment 1 [details]
3. Open and close pinned windows

OBSERVED RESULT
Icons sizes change size depending on how many windows are opened
(see attachment 2 [details])


EXPECTED RESULT
Icons sizes are fixed
(see attachment 3 [details])

There's not much room in your panel. The Task Manager is reacting by shrinking elements as needed. In this case, the calculation seems to be getting it somewhat wrong. :)

You're right. Thanks for putting more concise title!
