I'm used Awesomium before and Ultralight looks good! Thank you!
I'm edit "Browser example" to open "https://stats.quake.com/" instead wiki. Site looks correct, but when I'm scroll his continuously blinked. I don't know is problem with site css/markup or with Ultralight.
Subpage "https://stats.quake.com/heatmaps/" does not work, no 3D scene, only grey rectangle and few help icons showed. So sad if Ultralight can't show (yet) such websites.
