This issue seems to have improved, I presume with package updates since it was first reported. Animations are generally no longer jerky. Soft and hard reboot are generally no longer required. Keyboard Shortcuts appear/disappear smoothly. Remaining problems:
* Opening the Dash almost never works. Certainly not the first time or after having other windows have been open for a while. It behaves almost as though we have switch to the Dash pane, but it hasn't been rendered. As a workaround, if I open Dash then trigger Guake, Dash appears (with Guake behind it). * Closing or minimising windows generally works, except for the last window. Closing or minimising the last window fails completely, or starts the minimise animation but then halts. Either way, despite the window remaining visible, it is no longer clickable. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

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: * Not application specific. Minimizing is reliably slow/stalls with minimizing Firefox (including 29, I do not have a lot of bookmarks) or Pidgin, but I use those programs more often. * I am using an Nvidia Optimus machine with the default Nouveau driver - no `nvidia-prime`, no Bumblebee. I temporarily installed the latest stable Nvidia driver (including `nvidia-prime`) and it made no difference. * I did not experience this issue on the same machine running 13.10 (with Bumblebee). * I am running Maximus.
