At random times, Launcher does not respond to clicks too close to the left border of the screen

[Teo]

I have Launcher set up to not automatically hide (because it's buggy and it would stop showing up too often).

Usually, you can click on a launcher icon even on the leftmost column of pixels and it will respond to clicks.
Sometimes however, randomly, if you click on the very leftmost region, i.e. just next to the left border of the screen, it will not respond to click; you then have to click a little bit more to the right, inside the rounded rectangle that surrounds the icon, for it to work.
Then, after doing some random things with the mouse (switching focus between different windows, closing some), it behaves normally again

Can you still reproduce it? Seems to work fine here.

It's been a very long time since the last time I observed it, so I guess it's fixed.

I mean in 15.04. Most probably in 14.04 too, as I was still using it until very recently.
