Moving mouse out of plugin window to interact with browser makes the browser standstill

[lida...@gmail.com]

Hi,

We're developing NPAPI plugin for rendering buildings and the globe(something like google earth).

when our plugin loads many models in the scene(of course it takes much GPU and CPU), if I move the mouse out of plugin window to interact with chrome( click a link or switch to another tab ), the browser becomes

standstill, it reacts to my click action after a few seconds. The same problem does not happen in firefox.

It seems that, when I leave plugin window, the browser saves the GPU state or something else, and this results to the problem.

Is this the bug of out plugin or chrome?

Thanks
