[Bug 651297] [NEW] High Xorg CPU usage while scrolling a window

 

Public bug reported:

Binary package hint: xorg

A very hight Xorg CPU usage is detected when scrolling different windows. E.g. on Emacs window with a buffer full of text it's all 100%. 
I tried to replace repository nvidia-current drivers with the latest beta - no luck :(
