Can you try run a kernel with the following diff? It disables
powersaving and framebuffer compression and would help
narrow things down.

Thank you for your diff, but unfortunately it does not solve the
problem. Is there anything else I can try?
Is there a way on OpenBSD to get i915_error_state mentioned in
Xorg.0.log?
[ 3845.493] (EE) intel(0): When reporting this, please include
i915_error_state from debugfs and the full dmesg.
