(which AFAIK is normal, but didn't happen before).
Yes, that's normal and not related to this problem.
Note that the 'Attempted to destroy previously destroyed buffer.' messages would appear in the Xorg / LightDM log files, not in the terminal where you run the application.
Yes. Sorry if I was not clear, I grep'd through Xorg.*.log, and was not there. Anyway, please allow someone else to confirm that the patch works.
