Bug Description

Steps to reproduce:

 * 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:

 * 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.

Issue still occurs when Maximus is not running.

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.

I saw the same thing on one of my desktop machine. Just a few different :
No remains of windows but sometimes a windows refuses to close then mouse cursor slows down then, after some 10~12sec, all freezes. The dash usually opens but sometimes, have to open some other windows in front of it.

Additional info: I had an issue with the cursor flickering that was solved by disabling a mysterious extra display on my (Optimus) system. This had no effect on this issue.

Improvements:

 * Closing or minimising the last window has improved. The window usually disappears, however the global menu remains. Bringing up a hidden launcher in this situation sometimes fails.

Remaining problems:

 * Bringing up the Dash still fails most of the time.

Still affecting me pretty severely, I have all software updates.

I'm using a Nvida Optimus card as well. Occurs with both Nouveau and Nvidia drivers, as reported. I'm using the Intel card with the Nvidia drivers.

Minimize freezes the system about 90% of the time. I have to drop to shell and reboot to get usable system back. Launching Dash freezes the system occasionally as well. As long as I only task switch and show desktop, I'm mostly okay, but it's very irritating. I also disabled all the animations with CompizConfig Settings, but it didn't help much.

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).

I use Ubuntu 14.04 64 bits with NVidia propietary drivers (downloaded from Nvidia website).
I have the same problem only when nautilus manages desktop. The workaround for me is "gsettings set org.gnome.desktop.background show-desktop-icons false".

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.

Why is ubuntu bothering to duplicate the virtualbox packaging when Oracle appears to be both more current and supporting all of the Ubuntu releases in their own repo?
