The issue Bill is talking about and the one Andre is talking about are two separate issues.
Bill's momentary loss *might* be addressed by a change in the final version of XQuartz 2.6.3 (I'm not sure if it made the last rc):

Bill, if you could let me know if you still see the issue after updating to 2.6.3, I'd really appreciate it. I'm not getting my hopes too hight about it, but that might work around the issue.
Andre's issue is about quartz-wm likely grabbing focus and not releasing it for some reason (hence why the issue goes away when it is killed and restarted).
