1029480 - Ubuntu menu bar and dock are not always hidden in fullscreen mode

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Petruta Horea [:phorea], Desktop QA]

Attachment: Black line visible where the top bar should be

Reproducible on:
Firefox 31 beta 4 - 20140623175014
Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0
latest Aurora 32.0a2 - 20140623004002
Mozilla/5.0 (X11; Linux x86_64; rv:32.0) Gecko/20100101 Firefox/32.0
latest Nightly 33.0a1 - 20140623030201
Mozilla/5.0 (X11; Linux x86_64; rv:33.0) Gecko/20100101 Firefox/33.0
 
Steps to reproduce:
1. Open several pages in different tabs
(https://www.mozilla.org/en-US/firefox/31.0/firstrun/ , about:newtab , 
2. Open each of them in fullscreen mode (F11)

Actual results:
In some cases the dock and top bar disappear in full screen leaving a black line at the top. This is not the case for all pages.

Expected results:
Entering full screen mode should either hide Ubuntu bars without artifacts either leave them on. 

Notes: 1. The issue is not a regression, it reproduces back to Firefox 4.0.1. 
2. It doesn't reproduce on Win 7 or Mac OSX
3. I could see the black line on Ubuntu 13.04 64-bit, but not on the Ubuntu 13.04 32-bit same machine or Ubuntu 13.04 64-bit another machine.

Does this still happen if you remove the add-ons Ubuntu installs by default?

Comment 3

Yes, I could still see the black line with all plugins & add-ons disabled, starting in safe mode or after reseting Firefox.

Does this reproduce if you switch to Gnome Shell or XFCE?

I couldn't reproduce it after I installed Gnome Shell and XFCE.

I'm marking it as RWFM, thanks!

This might be a bug (or feature) in Unity. Maybe you could report it in Launchpad?
