Actually I double-checked this case with dailytech.com. It seems to be spending all of the cpu time in user-space in xwindows. So it seems that it is the new xwindows that has the problem. If you watch the 'TIME' field of top you can see that very little cpu time is attributed to firefox and quite a lot to X windows. So the windowing system is too busy to redraw mouse events even if we are scheduling it well.
