<br>
<br>
I don't know if it's really relevant, but here are my `dmesg` and<br>
`journalctl -b _COMM=gdm-x-session` ('xorg' files) before and after a<br>
session of Dota.<br>
I got two glitches and quit Dota right away. The main diff I see is<br>
between the xorg log, but I don't know if it means anything.<br>
<br>
Please see the attached tarball.<br>
<br>
Thanks!<br>
