Description of problem: When playing some video files in VLC using Haswell integrated graphics, the X server segfaults immediately. This seems to be a regression in some recent update as this wasn't happening before. Seems to be related to liva or VDPAU. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.99.917-18.20151109.fc23.x86_64 How reproducible: Every time Steps to Reproduce: 1. Play some video files (seem to be 720p H.264, not sure which exact characteristics are triggering it) 2. 3. Actual results: Xorg segfaults and drops back to login screen Expected results: Video plays successfully Additional info: Output from journalctl: Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: libva info: VA-API version 0.38.0 Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: libva info: va_getDriverName() returns 0 Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: libva info: Trying to open /usr/lib64/dri/i965_drv_video.so Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: libva info: Found init function __vaDriverInit_0_38 Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: libva info: va_openDriver() returns 0 Nov 30 22:10:18 haswell nautilus-autostart.desktop[2237]: [00007f2060c33278] avcodec decoder: Using Intel i965 driver for Intel(R) Haswell Desktop - 1.6.1 for hardware decoding.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '23'. 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 23 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.
Doesn't seem to be occurring at this point.
