Description of problem: I can see significant performance issues in GNOME Shell animations on Intel Graphics Media Accelerator 4500MHD and Intel HD Graphics 3000. I've also talked to several other users who have Intel cards and they experience the same. I discussed this with GNOME people and they say there have been no changes in GS animations between F18 and F19. So because it seems to be Intel driver specific, I'm filing the bug against this component. I also tried different kernels - from 3.8 to 3.11 and no changes. Version-Release number of selected component (if applicable): 2.21.8
If you can be quantative, that would help a lot. Perhaps a video recorded by a phone would help demonstrate the issue that you observe. There are 4 main candidates to check for regressions (and interactions between two or more): gnome-shell mesa xf86-video-intel linux (kernel). You've ruled out gnome-shell (but check just to be sure) and tested against the older kernels, which leaves just the ddx and libgl to downgrade and check.
Please see my comment on bug 946911. Using old graphics hardware that I guess doesn't do 3D - I don't even know what 3D graphics is nor why I should want it - things are fine under F18 with gnome in fallback mode. After upgrading to F19 top shows that gnome-shell is running all the time, using about 33% of the CPU in one case and about half that in another, while on a similar F18 system I don't see gnome-shell running at all.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
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.
