Description Stuart D Gathman 2012-02-28 04:14:35 UTC
Description of problem:
When Applications icon menu has a scroll bar, the entire list blinks at 4Hz.

Version-Release number of selected component (if applicable):
gnome-shell-3.2.2.1-1.fc16.i686

How reproducible:
Always

Steps to Reproduce:
1. Click Activities (or upper left corner)
2. Click Applications
3. Default category, All, will have a scroll bar and blink.
  
Actual results:
Blinking begins at 4 hz, accelerates for a few seconds, then starts at 4Hz again.  The icons, and their scroll bar fade in and out rapidly.

Expected results:
Steady icon list, such as you get without a scrollbar (I can click Games, for instance, and that is a small list for me).

Additional info:
The icons disappear, revealing the background underneath, then reappear.  Appearance and disappearance is smooth and controlled, it is actually a rapid fade in and fade out.  All icons do this in unison.

Here is a screencast of the blinking problem.  There is probably a filter to make it smaller, but I don't know what it is.

Comment 2 Stuart D Gathman 2012-03-01 01:50:17 UTC
Did an update, and now the blinking has gone away.  Here is what was updated:

Feb 29 12:54:30 Updated: setroubleshoot-plugins-3.0.27-1.fc16.noarch
Feb 29 12:54:33 Updated: setroubleshoot-server-3.1.3-1.fc16.i686
Feb 29 12:54:35 Updated: setroubleshoot-3.1.3-1.fc16.i686
Feb 29 12:54:41 Updated: graphite2-1.1.0-1.fc16.i686
Feb 29 12:54:43 Updated: tracker-0.12.10-1.fc16.i686

My guess is something went wrong at login that got corrected by the logout/login from the update.

Comment 3 Fedora End Of Life 2013-01-16 16:34:41 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 4 Fedora End Of Life 2013-02-13 20:25:05 UTC
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
