I’m trying to load some html that is animated using jQuery UI into a WebBrowser control that is hosted in a WPF app. The html is rendered very smoothly in IE9 but is kind of shaky using the WebBrowser control (see the html below)

I enabled the following IE features both under HKEY_LOCAL_MACHINE/SOFTWARE/… AND HKEY_LOCAL_MACHINE/Wow6432Node/SOFTWARE/…

FEATURE_BROWSER_EMULATION (using the value 9999)
FEATURE_GPU_RENDERING

http://msdn.microsoft.com/en-us/library/ee330731(v=vs.85).aspx

Still even with those features enabled I still get the content to render slowly. I also tried in WPF 4.5 to see if the “new” airspace could help but it didn’t

Does anyone have an idea on what could be causing that or what I could do to fix this?

Thanks for your help!
