Yeh same here Kitof, I'm very disapointed. Although playing video under 7.11 is working fine so I might stay with this release. Scrolling can hitch sometimes but its not bad enough to downgrade back to 8.34.8 as I also have to downgrade xorg-server too.

I'm going to search on the net for possible solutions but I don't hold much hope as 8.34.8 didn't have the error so why should this?
