Description alexhultman 2013-04-08 01:01:28 UTC
Description of problem:

Fedora 19 is tearing badly on NVIDIA graphics cards. V-sync is fixed for NVIDIA in upstream kernel and nouveau ddx according to Maarten Lankhorst as of 2012-08-22. Ubuntu has perfect v-sync out of the box yet Fedora 18/19 is tearing badly.

Geforce 210 as an example, is not tearing at all in Ubuntu but is a lot in Fedora 19 and 18.

Version-Release number of selected component (if applicable):
Fedora 19

How reproducible:
Always

Steps to Reproduce:
1.
2.
3.
  
Actual results:
Tearing

Expected results:
V-sync

I'm testing Fedora 19 on a livecd now and it still tears. Nouveau 1.0.7, livecd from 2013 04 30 (yesterday). I don't get how this can slip through all testing, is none aware of the tearing? I have a perfectly fine Geforce 210 that syncs perfectly using proprietary drivers, perfectly on Windows and perfectly on Ubuntu (nouveau). I have never seen Fedora actually doing vsync properly on nouveau. It's kind of useless to have all graphics torn into a billion pieces. Cannot watch video or anything. I think this is kind of a critical flaw.

I have the same problem on Fedora 19_64 with Gnome3 DE - Tearing when playback any video.

Comment 4 Fedora End Of Life 2015-01-09 17:51:39 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Fedora's policy to close all bug reports from releases that are no 
longer maintained.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 5 Fedora End Of Life 2015-02-17 14:57:03 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.
