Status changed to 'Confirmed' because the bug affects multiple users.

I also have similar problem after this update. Firefox constantly crashing, the only way is to disable hardware video acceleration. Chrome is not displaying anything until it's window is minimized and maximized again. Of course when I disable hardware acceleration it's working fine again. I don't play games, but I can provide any additional informations if you tell me how to do that.

i've been getting a lot of "this won't be fixed" from the people in ubuntu's irc support channel

Somebody knows any workaround for this problem?
