Strange behaviour with TextBox not showing string properly

Here is the text assigned to the Text property(pardon the bad quality):

Here is how the TextBox looks in the form:

It seems the spacing is now all screwed up. What could be the problem?

Edit: The TextBox is set to true for MultiLine, ReadOnly and WordWrap.
