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".

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.
