When a QWizardPage does not have a subtitle set and is currently blank, the banner section appears to consume the entire page.

That is, the whole page appears white. (In QWizard::ModernStyle - the Windows XP default)

However, as soon as a subtitle is set, even set to a single space, the banner section reduces to its normal size.

Furthermore, if no subtitle is set, but widgets are added to the page, although the banner is not present, the white background remains. The background should be gray.

Should the banner section even be visible if there is not a title, subtitle, logo or banner pixmap?

setOption(QWizard::IgnoreSubTitles, true) does not help to solve this.
