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).
