Public bug reported:
Release: Ubuntu Gnome 14.04 on both x32 and x64.
When enabling the desktop zoom accessibility feature, all the system
became unresponsive immediately after reaching the default zoom level.
The gnome-shell top bar disappeared, the mouse cursor couldn't move, and
I was unable to switch to another virtual desktop. After a few seconds,
the mouse cursor became able to move, but sluggishly, and interact with
the windows. The top bar didn't re-spawn, nor was I able to reach
another virtual desktop or to disable the zoom effect. The only I could
do was to drag the window around on the screen, which produced
artifacts, leaving blackness in its wake where it passed over the
desktop wallpaper.
I will not try to reproduce the bug again, having switched to Xubuntu
since.
I'm attaching my lshw output.
