Faulty task bar after upgrading to 11.3

Greetings everyone :slight_smile:
I upgraded from 11.2 to 11.3
My task bar looks a little bit “strange” after the upgrade

Here you can find out how it looks like

You can see the American flag that (left) that appears a little bit strange as well as at the right side the kwallet icon to be over the time. As I expand the taskbar to the left and then reduce it to the right these strange things keep happening not to the same icons all the time but to some of them.

What do you think it might be the problem?
Best Regards

You probably need to redo all plasma settings:
