WebBrowser is laggy

We are trying to use WebBrowser (WebKit based, on Windows) in our application, but it’s laggy… works really slow. On some computers totally unusable (like 0.5 second delay in everything), but even on good computers the delay is visible and makes it look really bad.

I think that it can be connected with disabled Hardware Acceleration for WebKit rendering system…

Any way to fix that?
