Shadow Border Around Images on Landing Page
Turn the stylized image settings off on the pre-designed widgets that automatically creates rounded corners and a shadow border.
When you create a split text and image panel for the portal Landing Page, it automatically creates rounded edges and gives the appearance of a shadow around the image that you upload on the header and footer. For darker colour backgrounds, this has no impact, but for lighter colours it shows up quite significantly. This setting should rather be an option and not preset.
