4.1 skin upgrade problem

Hi,

I've just tried to upgrade from 4.0 to latest 4.1.

Project compiled fine but all skinning went to hell.
Is there a howto that explains changes from 4.0 to 4.1?
Latest 4.0 works fine.

For example there is a problem with height of almost all form item (TextItem etc).

Best regards
