When set to autohide, launcher often won't show

[zzarko]

I installed 12.04 beta 2 64-bit and updated all packages. If I set autohide behaviour for launcher, very often it won't show when I move mouse to the left side (it is set to reveal when mouse is on the left side). Only it's shadow is shown (a few pixels wide) along the left edge of a screen, for about 1 second, and then it fades out. If I repeat moving mouse to the left side, it eventually shows, after 1-4 retries.

In the screenshot provided, you can see that only shadow of the launcher is shown when mouse is moved to the left edge.

Status changed to 'Confirmed' because the bug affects multiple users.

Running 12.04, Unity 2D, Ndivia 6150 chip, Nvidia driver 304.51, running on an external monitor, with the laptop monitor disabled.
After a recent update on 9/25 or 9/26, the launcher, which is set to autohide, does not appear when moving the mouse to the left side. Workaround is to use the left Window button to get the Dash/launcher, select the "System settings"/appearance/behavior and turn off autohide, so the launcher is always present. Usinging the laptop display instead of the external monitor does not fix the problem.

Ubfan, that is being tracked as bug 1057000

plus from what I can see you are using Unity3D not 2D

@om26er -- I'm not running Unit 3D. Nvidia 304.60 fixed the problem for me, but it takes 2 sec for the launch bar to appear -- too slow for me, so I leave it visible now. Driver 304.63 worked too, after some initial problem which had the GUI login stuck in a loop -- looked like some old .X* files in my home directory caused some issue.
