Description of problem: Kwin from kde 4.5 beta 2 crashes in some circumstances. Sometimes i just change some options not related to effects or kwin at all in kde control panel and the system freezes. Version-Release number of selected component (if applicable): [edney@padme ~]$ rpm -qa | grep xorg-x11-drv-intel xorg-x11-drv-intel-2.11.0-4.fc13.i686 [edney@padme ~]$ rpm -qa | grep mesa mesa-dri-drivers-7.8.1-6.fc13.i686 mesa-libGLU-7.8.1-6.fc13.i686 mesa-libGL-7.8.1-6.fc13.i686 mesa-libGL-devel-7.8.1-6.fc13.i686 mesa-libGLU-devel-7.8.1-6.fc13.i686 [edney@padme ~]$ rpm -qa | grep Xorg xorg-x11-server-Xorg-1.8.0-12.fc13.i686 [edney@padme ~]$ rpm -qa | grep kdebase kdebase-runtime-4.4.85-1.fc13.i686 kdebase-workspace-wallpapers-4.4.85-2.fc13.noarch kdebase-workspace-4.4.85-2.fc13.i686 kdebase-libs-4.4.85-1.fc13.i686 kdebase-runtime-libs-4.4.85-1.fc13.i686 kdebase-4.4.85-1.fc13.i686 kdebase-workspace-python-applet-4.4.85-2.fc13.i686 kdebase-workspace-devel-4.4.85-2.fc13.i686 kdebase-workspace-libs-4.4.85-2.fc13.i686 How reproducible: At least one use case i can reproduce. Steps to Reproduce: 1. remove ~/.kde/share/config/kwin*rc files 2. log in 3. activate desktop effects on control panel 4. try to log out 5. crash Actual results: kwin crashes sometimes, sometimes desktop freezes. Whenever it happens i can't activate desktop effects again. I have to stick without it or with xrender effects which is very slow. Expected results: A smooth compositing experience almost like the one i had on Fedora 12. Additional info: I came here from this bug on kde specially because of comment #30 https://bugs.kde.org/show_bug.cgi?id=240956 [edney@padme ~]$ lspci | grep -i vga 00:02.0 VGA compatible controller:

This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '13'. 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 13'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 13 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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
Hi there. Running Fedora 15 now, there's no such problem here. Thank you.
Thank you for letting us know.
