Hello
Normal look of pager. Active Desktop is marked with a gold line around.


After restart / login get this form

Gold lines on the upper side covers three desktops in the pager, and all are connected.
To achieve a normal look need to make a change in the Pager Settings, just to apply some change.

Other theme for the pager the same thing.

After restart / login get this form

Some idea.
Thanks

This looks like a sizing issue. If you change the height of the panel temporarily does that correct the issue?

You're right, the height of the panel affect to this thing.
With greater height of the panel, no problem.
