* Only with blob-images, the box on the top right loads very slowly.
* Scrolling down and up can make some parts just white, but with blob-images it's longer white and I'm unable to grab the scrollbar.

This looks like spam to me. Please file a seperate issue if you really see a WebRender issue.

Be sure, these sites are being well-tested and they have a high priority. ;) https://twitter.com/junglecode/status/933907846671900672
