Public bug reported:
I use a three-monitor setup with Ubuntu Dock configured to appear on all
displays and auto-hide enabled.
Steps to reproduce:
1. Connect and enable three monitors.
2. Set one monitor as the primary display.
3. Configure Ubuntu Dock to appear on all displays.
4. Enable auto-hide for the dock.
5. Move the mouse pointer to the dock edge on either secondary monitor.
6. Try to move the pointer over an application icon.
Expected result:
The dock should appear and remain visible while the pointer is over it,
allowing an application icon to be clicked.
Actual result:
On the secondary monitors, the dock repeatedly hides and reappears when I move
the pointer onto it. This produces a blinking/flickering effect and makes the
application icons difficult or impossible to click.
The dock works correctly on the primary monitor. The problem occurs on
the other two monitors.
Frequency:
The problem occurs consistently.
