Comment 38 for bug 1295909

I've had problems with window spread before, too, but only on a laptop with Nvidia graphics. On another one with Intel graphics, it works flawlessly.

Anyways, after upgrading to vivid, I tried to enable window spread using unity-tweak-tool again, and I got that freeze plus (after a while) crash again. But this time, it was so bad that I could not even log in any more. Afer entering my password, and after a second or so, I was always presented with a completely white (or light gray) screen, and after a mouse click, there was the login screen again. A reboot did not help, either.

So after removing some config files in my home directory also did not help, I removed all nvidia-* packages. Now I could log in again, and finally I had a chance to switch window spread off again! (By the way, it still crashes.)

I also got many apport crash popups after being able to login again (Xorg, compiz, apport).

I guess I was hit by multiple bugs at once. Do you need any additional information?
