Help documention style broken in v4.2 and later

I was ignoring this for a while but checking older versions of QtCreator shows that the built-in help formatting is somewhat broken in v4.2 and later (including the latest at this time v4.3.1).
I am attaching screenshots of the difference between the help rendering in v4.3.1 (left) and v4.1.0 (right).
If you can't view the attachment: the text listing the class types and functions is vertically overlapped so much that it is hard to read, and even harder (impossible?) to click on the right hyperlink for a particular member function.

Do others see this? Can I fix it by adjusting some style sheet somewhere?

Thx for any help
