Can I roll back the recent update?

Since the most recent update the game plays awful.   It has never been smooth but now it is awful.   Aside from the bug I posted, it jerks around from screen to screen without me doing anything. It happens so fast I do not even know what is being displayed before it is gone.  Like earlier versions it really slows down when using bigger games.    My turn comes up and before I can do anything it overlaps multiple screens instead of letting me handle them one at a time and then coming up.   Also It is only really using two of the processor threads on the CPU  If they can make it use all four and balance tht out it would help.  If I go to fast moves and fast batles it is worse. Thing hapen so fast they do not even wiat for me to do something. Playing on an alienware X17R2.
