A fresh set of files for you, for a fresh artifact.

Files include screenshot, dmesg (minus several thousand lines of output from
iptables that I assume you're not interested in), Xorg.0.log, xwininfo and
xprop (redacted).

The artifact occurred while trying to copy some selected/highlighted text with
a right-click.  The copy window never actually appeared, other than the
artifact you see in the screenshot.  Note that the artifact is "top-level" and
obscures all other windows.

Please advise.

Thank you
