I don't know when it started. It certainly is a problem in recent
versions.

You can see how it inserts wrong namespaces such as
Qt::Orientation::Vertical instead of Qt::Vertical (which is then not
recognized).

I currently correct the UI files manually in an editor after having
used designer. Strangely enough, I also did not find any report about
it.
