I'm using Docky on XFCE4.
After doing some updates and changing configurations, I suddenly had a weird visible "line" at the bottom part of my screen. Seemed like a graphical glitch, but windows would snap to it, so it was somewhat "real"
[SOLUTION]
In XFCE's settings, enabling the following causes this shadow-line to appear (only when Docky's running):
Code: Select all
Window Manager Tweaks > Compositor > Show shadows under dock windows
