Ubuntu 15.10 Unity Dash freezes after returning from locked session

[Stacey L]

I'm using Ubuntu 15.10 on an Asus laptop. I've noticed that the Unity Launcher or Dash resting to the left of my screen freezes as well as the menu in the upper right corner freezing as well after I return to my main account after switching users.

Steps I use to reproduce the problem.

1. Select Menu button in upper right corner.
2. Click other user account...
3. Switch back to original account via same menu.
4. Unity Dash doesn't scroll, nor does the main menu (upper right corner work)

Solutions I've found

1. Pressing Control + Alt + L to lock screen
2. Unlocking the affected user account.

I'm wondering if there is a fix for this, or if any other users are experiencing this.

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

I'm seeing the same thing after upgrading from 15.04 to 15.10.
Also using an Asus laptop (Zenbook UX31A) with multiple user accounts.

I have the same issue with 15.10. Hope this gets resolved before the LTS.

For me it happens on two machines now - one having 15.10. the other 15.04. Was not the case before a while, so must have been introduced by an update (not dist upgrade)

(it happens occasionally, maybe 2-3x per week, usually afer logging in after a suspend. Can't click any icons in the left panel or upper right menu. Dell M3800 and Dell Inspiron)

I am on an Asus TP300L Laptop and this happens at least every other day, I just close the laptop and re-login.
