Comment 5 for bug 63051

I found this problem too. After finally getting X to start, I find that Firefox or any other applications' scrollbar doesn't operate as well as it did before. In fact, I don't understand the fix that Mark has put up here. I have an nVidia display and it wasn't supported earlier either.

I donot know if this is a problem with X or GDM or anything else. But I don't know how to fix it either.

Dragging a window causes the window to leave traces behind. It is simply irritating. None of these were my initial settings.
