Since this week, Blend4Web applications (both my own applications and the provided example applications) do no longer load properly in Chrome and Firefox. Loading an application in dev mode either returns in a WebGL: Context lost error and it does not load at all or if the application loads it takes forever and runs with a maximum of 5 fps. A few weeks ago, the application ran without issues with 60 fps. Currently, loading a blend4web application also takes up immense processor resources, with up to 100% CPU usage. At this state, Blend4Web is barely usable.
