Bug Description

Expectation
When 'auto-hide' is enabled for the launcher and the reveal spot is set to top-left the launcher should appear whenever the mouse cursor is placed in the top-left corner regardless of the path the mouse cursor takes to arrive there.

What Happens
If you begin with your mouse cursor at the left hand side of the screen and move it up into the top-left corner, the launcher will often not appear correctly. When the mouse cursor moves into the top-left corner, you can see what looks like the drop-shadow of the launcher appear, but the launcher itself does not.

Please feel free to contact me @eikonomega for additional information.

I have the same problem when I use the top left hotspot or the entire left edge. I have to make sure I move the cursor over with sufficient velocity from the right to get it to reveal. This might be useful if it appeared too easily. At high sensitivity it is not too bad, at low sensitivity I could hardly get the launcher to reveal at all.

I can't get the launcher to show up again except when pressing Alt + F1 or the Windows key. No matter what settings I try, it just stays unimpressed by any of my mouse moves and hides itself in a parallel universe or wherever.

I have some news: I'm actually running Ubuntu inside a VirtualBox VM and my problem was caused by the mouse integration. If you have mouse integration enabled, as soon as you reach the display border the mouse leaves the VM. Therefore the launcher won't show up again. Therefore I don't think it is an Unity bug (maybe not even a bug at all).

This has affected me since Ubuntu 12.10 using side reveal. Currently using 13.04 the frequency seems to have increased compared to 12.10. I have not tested using corner reveal. Now it may take 30-40 attempts to get the launcher to appear at times.
