@urbenlegend why do you think this is a steam issue and not a mesa issue? This should be reported to the freedesktop bug tracker.
This may very well be something in Mesa, but the crash only happens with Big Picture. Any other 3D application works fine and doesn't crash. I can run Steam games just fine.
@urbenlegend: Can you reproduce it with the steps in https://bugs.freedesktop.org/show_bug.cgi?id=92258#c6
I'm wondering if these issues are related.
No, those steps work perfectly fine for me.
@urbenlegend: I've tried a few things, but I can't reproduce it yet. Do you know what version of gnome you are running? I'm running 3.18.
I am running 3.18 as well. I'll test again tonight.
Per the 2017-01-05 steam beta update, does this issue still occur with the beta client?
Nothing extracted yet.
I can make Big Picture mode crash Xorg whenever I enable DRI3 in the Intel graphics driver and try to change my volume. I can reproduce this 100% of the time on Fedora 23.
Steps to reproduce:
Disabling DRI3 causes it to not crash.
