Hi, I know this has been a issue with X11 on OS X for many years and, as I was being plagued by it very frequently today (happening every few minutes!), I did a little research. Apologies if all of this is known already (it's hard to remember what has been reported in the past and I don't know an easy way to search the list archives; I didn't see this in the bug report #58), but I hoping this is new info and it helps track down the problem.
Anyway, what I did was run xev against the root window (I am not running in fullscreen mode). Each time focus is lost I see this event:
KeymapNotify event, serial 22, synthetic NO, window 0x0,
keys: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
My only clients are urxvt windows (per xlsclients). When losing focus I'm working exclusively in the same urxvt window---not using the mouse, not switching windows. I'm only typing. Within urxvt I'm running tmux, and the focus loss seems to generally happen after switching virtual windows (using F keys) and then typing, and that generally seemed to be when I sent a page-up into the other window. Unfortunately it is not consistently happening, and was occurring much more frequently earlier this morning than it is now.
The other thing I noticed is that, after losing focus, if I wait without doing anything with the mouse or keyboard, X11 returns focus to the window I was working in after ~5 seconds, and I see this event:
PropertyNotify event, serial 22, synthetic NO, window 0x141,
atom 0xf5 (_NET_ACTIVE_WINDOW), time 2588774827, state PropertyNewValue
Is there anything else I can be doing to try to track down the problem?
I'm running XQuartz 2.7.4 on 10.8.2. With this problem, X11.app itself retains focus, but during this focus loss no X11 client windows have focus (except, presumably, the hidden root window).
Thanks!
Brian
