Another problem with Blender, related to opengl.

Shadows do not work with EEVEE using opengl, changing to vulkan in
config settings, shadows become visible again.  May be some Intel
drivers issue?  The machine is the same one from my last report:

  https://marc.info/?l=openbsd-ports&m=176259404019247&w=2

But the problem doesn't end there, as the subject mentions, when I
change some settings in Blender, for example in "world", trying to
change color to "sky texture" from Preetham to Nishita my graphics
completely freezes.  I can still ssh from another machine but even after
killing the processes or even running reboot the system is unresponsive.
This happens using opengl but not with vulkan.
