I get this issue constantly with all updates applied as of today:
(1) Start a new desktop session
(2) Open a full-screen Thunderbird on workspace 4
After doing those steps there is about 50% that Unity renders it's windows below all other windows.
Also, it not only affects the launcher, but also the dash/lenses and the task switcher (ALT-Tab). If those get constantly rendered below all other windows it renders Unity unusable.
I can confirm that this bug is NOT fixed.
