Usability Face Palm

Opening in full-screen on a big monitor reveals this gem:

The text reads: “Es können nur Karten mit max. 1024×1024 Pixel angezeigt werden. Bitte veringern Sie die Auflösung Ihres Bildschirms oder minimieren sie das Browserfenster.” (in english: “Only maps with max. 1024×1024 pixel can be displayed. Please lower the resolution of your screen or minimize the browser window.”)

After blacking out every other pixel of my screen with a pen and minimizing the browser window, I am thoroughly disappointed with the result!
