I'm experiencing the same sluggishness / slowness with the Dash and login screen using a fresh install of Ubuntu 12.04 32-bit (Ubuntu 3.2.0-24.37-generic-pae 3.2.14) on an Asus Core i3-based laptop (2GB RAM, Intel HD Graphics). Otherwise, the system is snappy, Unity 3D is turned on, 1080p video plays fine using VLC, etc.
Like the OP stated, using a wallpaper or solid background color doesn't seem to make a difference in the Dash's performance, and I too am noticing whatever background I may have set is getting shifted downward whenever the Dash is opened. The login screen shows similar cursor / selection lag. Once logged in, the desktop (but not the Dash) appears to perform just fine. Compositing is enabled, no delay when moving, maximizing / minimizing windows, etc. version.log: Ubuntu 3.2.0-24.37-generic-pae 3.2.14 ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/990002/+attachment/3134284/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990002 Title: Slow Dash animation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/990002/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
