Comment # 3 on bug 874786 from Otrebor Igorig

Hi thanks for feeding back on this bug.

I've first applied all available patches to date.
The I retried to run glxgears - no change, still crashes.
After that I added my account to the video group.
Tried to re-run glxgears - still no change.

rpm -ql Mesa-demo-x-8.1.0-4.1.2.x86_64
/usr/bin/glxgears
/usr/bin/glxinfo
/usr/bin/pbinfo
/usr/lib64/mesa-demos
/usr/lib64/mesa-demos/xdemos
/usr/lib64/mesa-demos/xdemos/glxgears
/usr/lib64/mesa-demos/xdemos/glxinfo
/usr/lib64/mesa-demos/xdemos/pbinfo

glxinfo crashes as well:

Trying to run glxgeras is just a test case.
This error also prevents to run qt5 based gui programs over ssh e.g.:

rpm -qf /usr/bin/designer-qt5
libqt5-qttools-5.1.1-1.1.x86_64

What's interesting is that the older QT4 designer works as expected.
libqt4-devel-4.8.5-5.13.1.x86_64

I have not yet made the switch to QT5. To me running X11 tools over ssh is an
every day use case. So, this bug prevents me to make the switch.

Thanks for helping me investigating this.
