Monitor layout
SUMMARY
I have a laptop that's connected to an external monitor. In the Display
settings, I have the external stacked above the laptop display so that its laid
out vertically (refer to monitor layout in attachments). The external display
is marked as primary so that's where my main panel resides. If I disconnect and
reconnect the external monitor and then drag a window close to the panel so it
unfloats, it causes corruption to appear in the secondary screen. The
corruption appears to be a gaussian blurred version of the desktop wallpaper.
STEPS TO REPRODUCE
1. Connect an external monitor to a laptop and stack it above the laptop
display in the Display settings
2. Mark external as primary so that panel is displayed on it
3. Disconnect monitor and reconnect
4. Move a window close to the panel so that it unfloats
5. Notice a gaussian blurred bar on the secondary laptop display.
OBSERVED RESULT
A weird blurred bar is shown on the secondary display
EXPECTED RESULT
No weird bar is displayed
