This sounds strangely familiar, but is not normal behaviour. What is the
behaviour of the scrollbars when you preview the form in Qt Designer?
(You may have to add some content to the QPlainTextEdit to make sure you
get scrollbars.)

Usually, scrolling should just work "normally". If possible, can you put your
.ui file somewhere for us to take a look at? I'm wondering if there's
something strange in the way these widgets are configured.

By the way, you don't say which platform you are running on, or the versions
of Qt and PyQt you are using. Those pieces of information might also be
helpful in figuring out the cause of the problem.
