Hi, start by sending a proper bug report, ie. include dmesg, /var/log/Xorg.0.log outputs,... See https://www.openbsd.org/report.html for details. Next /usr/xenocara/README[1] has some hints on how to get a core file out of the X server. Please try to get one an extract a stack trace using gdb from ports.
