This is generally caused either by applications that do Xlib calls in
their Xlib error handler, or by multi-threaded application that use a
non-thread-safe version of libX11.

Normally libX11 is built on OpenBSD to be thread safe, but it's
difficult to say if it's really the case, given the number of difficult
problems in this area.

I can't reproduce this on my machines for now. Il will try later on more
 machines/graphics cards.

Sorry not be be able to be more helpful.
