Comment 21 for bug 416073

Sorry for the delay with providing info...

extremetuxracer 0.4-2ubuntu1, which is a default version from karmik repo.

I'm using default KDE compositing, kde-window-manager 4:4.3.1-0ubuntu8, again default karmik version

Secondly (it looks like I've forgot to mention it in the original report), the regression I'm talking about can be observed in the fullscreen mode; if the application is fullscreen, the performance does not depend from compositing. I mean, Hardy's 60 FPS and Karmik's 30 fps are both fullscreen.

If I'm running etracer in windowed mode, it shows the same lower performance (30 fps) if compositing is enabled and even lower performance (15-20 fps) with compositing. So there are two separate bugs here, I think.
