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.
