Description Luiz Romário Santana Rios 2013-10-20 16:04:26 UTC

Description of problem:
If the desktop OpenGL compositing is enabled, the screen flickers when any component is fading out. This is especially noticeable with widgets like Homerun, for example. This doesn't happen if the XRender compositing is enabled neither it happens on GNOME.


Version-Release number of selected component (if applicable):
2.21.12


How reproducible:
Almost always.

Steps to Reproduce:
Make anything fade out a few times and you'll probably hit it. One way of doing this could be:
1. Open Homerun
2. Run any application

Actual results:
Screen flickers

Expected results:
Screen shouldn't flicker

Additional info:
This is an Asus Zenbook Prime (UX31A), running on Intel HD Graphics 4000, according to the manufacturer. lspci gives me:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

Bug 307112 from KDE is relevant to this issue. As a workaround, disabling the Blur effect solves the problem.

Comment 2 Fedora End Of Life 2015-01-09 20:19:04 UTC

This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 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  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

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.

Comment 3 Fedora End Of Life 2015-02-17 17:45:36 UTC

Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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no longer maintained, which means that it will not receive any further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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

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