Steps to reproduce: * Launch Unity desktop session * Minimize current window or alt-tab between windows * Reveal launcher to click on application * Click `Super` to bring up Dash * Hold `Super` to bring up Keyboard Shortcuts What should happen: Action completes smoothly and quickly. What happens instead: * Action may be slow / animation jerky. * Action may stall (animation frozen on given frame, e.g. window partially minimized) - initiating another action cancels first action and second action may succeed (most often calling Guake with F12 seems to solve the issue) * Action may freeze - cursor no longer moves - a soft reboot (Alt+PrtScr+REISUB) usually works, otherwise a hard reboot Notes: This occurs on Ubuntu 14.04 and 14.10. See https://bugs.launchpad.net/bugs/1314587 for a downstream bug report. It was suggested there that an upstream report would be helpful. I'm not sure which X.org component this applies to, if there is any additional info I can provide please let me know (also see downstream bug, linked above).
Please attach the Xorg log file.

There is no mention of nouveau anywhere in here, indications of the other bug are that nouveau vs nvidia doesn't matter, and I see no indication of DRI_PRIME ever getting set. I believe this is miscategorized, it's unclear to me why this is in the fd.o bugtracker at all, sounds like some ubuntu thing.
