Lots of lagging after upgrade of xorg.

[Leslie Jensen]

Hello list.

I'm experiencing a lot of lagging after I've upgraded xorg. I use XFCE 
and just changing from one desktop to another now feels really slow.

If I click on a button in an application I have to move the mouse 
pointer before there's a reaction to the click.

In a terminal window I also have to move the pointer outside before the 
input from the keyboard is registered.

Maybe it's a mouse problem. Anyway I need some help if it's a setting 
that has to be changed.

My system, 8.2-RELEASE-p6, worked well before the upgrade of xorg.

Thanks
