Hi,
I've noticed that for whatever reason, since the page layout was changed the headers are all magnified or distorted. In the image below, you can see that the text is grainy as are the vector bars on the right.

Before the update, I had the below banner and things mostly worked fine.

To even get the grainy results I have now, I had to centre the banner in an oversized image otherwise it would always cut off text.

Can anyone at Confluence please confirm what image size we need for the header to work correctly and not appear grainy, magnified or distorted?
