Title bar is not shown when Marta starts in full screen

[IgorKrupenja]

1. Open Marta.
2. Enter full screen.
3. Exit Marta while in full screen.
4. Open Marta again.

Marta correctly starts in full screen. However, the title bar is missing:

5. Try moving/copying a large file.

There is no progress indicator since title bar is missing ☹️

6. Now, exit full screen.

Traffic lights icons overlap the directory path:

And no progress bar for file operations as well.

Workaround: exit Marta when not in full screen and open Marta again.
