Ok, you are right, it only happens with depth test enabled.

The strange thing is that it creates these artifacts in my ray caster,
where I get exactly theses holes but both front/back faces have the same
interpolated positions, so depth rejection should not create holes because
another triangle should be have rendered to that pixel first.

Anyway, I think the depth test should still not generate these rejection
pixels, since it will create problems in e.g. depth peeling and other
algorithms as well.
