[Bug 815996] Re: Desktop occasionally freezes/locks up when switching workspaces


On 14.04 the same: when I switch workspace in windows oftentimes it get stuck on workspace mode (where I see the 4 workspaces). The moust pointer becomes a hand and there is no way to switch back to normal mode. This seems to happen more if there are windows refreshing (e.g. a tail in some terminal window). I typically get out of this by kill -HUP <compiz> from Ctrl+Alt+F1
I could not get out of it disabling snapping windows because it said unity plugin requires.

Bug description:
  I'm assuming the issue is related to Compiz, but I'm not 100% sure.
  When I'm switching workspaces, it occasionally locks up (becoming more
  frequent). Most of the time, I'm going from the current one down
  (Ctrl+Alt+Down Arrow), and it freezes mid slide. Typically, I'm able
  to correct things by backing out to a terminal then returning
  (Ctrl+Alt+F1, pause, Alt+F7), but sometimes when I return the dual
  screen setup acts as one large screen (windows are stretched to the
  full width of both screens) and many of the windows collect on the
  first workspace.

  Ubuntu 11.04 (Classic)
  All packages up-to-date.

  If there are any logs/etc that would be helpful, let me know.
