Hello,

I just installed LibreOffice fresh on my Arch linux system.

I tried to setup to get automatically the A4 papersize.
Finally, I have succes in that.

Then I setup the View of LO and choose small icons in the menubar.

Then I close LO and after that I start it again.

I get black menubar and when want to change back my settings ( I found
it difficult to in the black ) I can't get back the gray menubar.

What happened?
How can I solve this problem?
