This is kind of a vague bug report... without tangible measures or error messages or something, it's going to be hard to say for certain what the problem is exactly, or to know when it's fixed.
But anyway... If it is indeed a mesa problem, well I've posted a PPA with the 8.0.3 mesa which you could test: https://launchpad.net/~bryce/+archive/mesa-803 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/906021 Title: Opening the dash or alt+tab it is very slow and laggy To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/906021/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
