The smoke display was rewritten in 2.8 and does not suffer from these types of artifacts anymore.

Philipp Oeser (lichtwerk) added a comment to T60647: regression - corruption of files.

dustBin's displacement in //assets/dustBin.blend on the rim object (called Cylinder) is making problems.
I assume this is still not using the 'new' displacement node in that file (it will be there when you open that file, but that is probably because cycles adds that automatically when seeing an old file)
And when linking, this automatic insertion fails, see T54504.

jan bauer (janb) added a comment to T60647: regression - corruption of files.

@Jacques Lucke (JacquesLucke) if I don't save the file (use the original directly), it just hangs forever, but no crash anymore. I still have to kill as it will take 1 core of CPU forever(waited 5minutes at 25%) just after rendering. Actually, the crash was "better" as I didn't had to kill the process myself. It seems it's due to the compositing phase?
However, the file corruption when saving still happen with this strange portal being added in the left corner of the room.

Does the crash happen in the newest Blender 2.8 build, even when Render Samples is set to 1?

There's no bug here:

  • To make numpad 1/3/.. switch to ortho mode, enable Auto Perspective under User Preferences > Interface.
  • To have the result of the boolean visible when you move away the sphere, you have to apply the modifier first.

Proper way to deal with this would be to move every CPU kernel into a namespace. That would ensure linker never re-uses "wrong" microarchitecture implementation.

Brecht Van Lommel (brecht) closed T53886: cycles regression: increased noise in overlapping transparent shaders as Archived.

I'm aware of this, it's an intentional trade-off we are making. With Russian roulette you get more noise in simple cases, but it helps in more complex cases like transparent hair. The two are difficult to distinguish for the renderer and it's generally not helpful to do so in real world scenes where you have a mix of these.
