There is a small yet annoying gap between unity-panel and the upper edge of the screen

[Konstantin Molchanov]

I've attached a screenshot, please pay attention to the very top of it.
It has nothing to do with the monitor settings, I see the bug at a notebook where I neither haven't nor couldn't have changed any settings.

Do you have the same issue with lightdm (when you log in) or is it only visible in unity? It might also help if you attached your /etc/X11/Xorg.conf file.

[Konstantin Molchanov (moigagoo)]

Lukasz,
this bug is only visible in Unity, in LightDM the gap is not present.
Unfortunately, there's no Xorg.conf in /etc/X11/ so I can't attach it.

[Konstantin Molchanov (moigagoo)]

I also noticed that Dash takes the whole top without a gap, too. See the screenshot.
