Launcher auto-hides prematuraly

[Patrick Gillespie]

This is a peculair bug. I can reproduce it with the following:

1.) The launcher is only set to be revealed by mousing to the upper left corner.

2.) I switch to another workspace.

3.) I scale (show windows).

4.) Then, when I mouse over to the launcher, the launcher will always prematurely hide, even if my pointer remains on the launcher - making the launcher impossible to use.

To reproduce. Further details:

1.) I start out on workspace 1
2.) Switch to 2 using (show workspaces).
3.) (Show windows).
4.) Then mouse over to the launcher and it will prematurely auto hide.

Addendum:

Curiously, if I switch back to workspace 1, the bug will go away. That's as far as I've gone.

Auto-hide
- does not work at all on the VirtualBox
- does not works on a fresh install on a Acer AspireOne
- works at time (it is useless) on a Acer TravelMate 6593 even with the max sensitivity
