Comment 1 Olivier Fourdan 2019-09-17 07:49:03 UTC
The crash occurs in `miSyncInitFence()` so possibly related to the sync/fences changes for nvidia PRIME offloading patches (worth noting this is on i686)

  https://gitlab.freedesktop.org/xorg/xserver/commit/82f01ad7869e3f2be51e41a8246dab5982bbc36a

Although this is just a wild guess... Could you install the relevant debuginfo packages and redo the backtrace/bt full in gdb?

Meanwhile, you should be able to avoid the crash by switching to Xpresent for vsync:

  $ xfconf-query -c xfwm4 -p /general/vblank_mode -s xpresent
