GNOME Bugzilla – Bug 171174
Crash under Xephyr
Last modified: 2009-06-14 21:53:42 UTC
Distribution/Version: Gentoo Metacity 2.8.6 falls over a lot under Xephyr. Verbose log file follows. This one was generated with just Xephyr and xlogo.

Probably related to, if not a duplicate of, bug 169684.
I'm not so certain. #169684 never showed up in 2.8.x at all-- and it's reproducible enough that I'd have noticed it there.
Does the backtrace change if using METACITY_SYNC=1 ? (so we call XSynchronize())
that log was generated with METACITY_VERBOSE=1 METACITY_USE_LOGFILE=1 METACITY_SYNC=1 DISPLAY=:1 metacity & if you'd like to see it unsynced i can do that too.
Nope, unsynced is useless, thanks. Unfortunately synced is probably pretty useless here too... X has the errno problem (hp's law of errno: "if you have only error codes with no error messages, the error codes will get overloaded and become meaningless and unhelpful") So, deeper poking to see what is being drawn to what with which gc is required, and then figure out what part of that causes badmatch.
Metacity does not fall over under Xephyr for me. Reporter, are you still having this problem with a modern version of Metacity?
