Bug 60003 – [Qt] White screen displays when using MiniBrowser with DrawingAreaImpl

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Qt

[Yael]

When enabling DrawingAreaImpl in Qt, a white screen is displayed instead of the web page.
That is because the page client is not returning its size correctly.
A patch is coming.
