Windows size change to be to big for screen.

[Knapp]

Hope this is not a repost I am new and did not see my post or any answers.

Hello I switched my KDE amd64 from English to German and now many of
the screens (program windows) are to big. Firefox still works but
system watch is about 3 cm to big for the screen along with some
others.

What is up? How do I fix this?

Also the little cool auto updater is no longer working for some
reason. Maybe a different reason. I think I turned it off but don't
know how to turn it back on.

Thanks Douglas
