How do I force to disable desktop effect "Sheet"? I activated it and now my computer is too slow...
How can I remove it? Or via terminal?

You can change which effects are enabled/disabled through System Settings: System Settings -> "Desktop Effects" -> "All Effects" (tab) -> uncheck "Sheet" -> Apply.
This is for KDE 4.8/4.9. In previous versions the path or names were different IIRC.
Or, you can try changing "Compositing type" in the "Advanced" tab and see if it works better.
