Looks like some work might be happening on the compositor (exciting!). I started collecting some ideas in a DevTalk thread a while ago, but unfortunately got busy and mostly abandoned it. It might be worth checking it out again.

This appears to have resolved itself. Not sure what happened, if it was a Windows update or what, but I just tried it and it's working fine now.

I have to agree with Duarte.

I just checked it again and there's some inconsistent behavior happening.

This issue is still happening for me. Attached is a screen recording of it using the latest 2.82 Beta

Further testing appears to show that adjusting the number of particles fixes the problem. So for example, if instead of the default 1000, I change it to 999 or 1001, the the dynamics work again.

Derek. It appears you are right. I tried it with my second test file, that had the dark small squares, and turning that value to 0 solved the problem.

I hear you. But this was the exact glitch I created this bug report from. Those images are created from the same file I posted when I created the bug report back in July.
Maybe the dark black squares are a different issue. I’ll try later today with the other file I posted.
I did restart the render every time. Attached are render images of both before and after adjusting the empty space parameter and also one of the fix I found, moving the ground plane slightly (0.01)
The empty space parameter actually made it worse when turned to 0. That said, playing a little more with it I found that my ground, was overlapping the edge of the domain, moving it slightly fixed the problem in this scene. I'll need to do more tests to see if that is always the case, or if it just happened for this specific scene.

Thanks Sebastián. This is great! There's probably still some problems, but at least this makes the smoke simulator usable again until MantaFlow comes out.

Question for the devs. Is there a reason why we can't revert back to 2.79's behaviour. I understand that there are some bugs in it, but for the most part it was working in 2.79. Now there's features we can't even use.
Can we just bring back the old behaviour, even with the bugs, until we get MantaFlow? Maybe it's set as an "experimental feature" .

Any plans for this to be fixed before the final since the launch has been delayed with RC2?

Here's another example. This time in a Windows 10 machine with an 1050ti card and up to date drivers.
You can see the small dark areas on the floor are shadow glitches.

Thanks for the quick reply @Brecht Van Lommel (brecht).

This appears to have been fixed in the latest build.

Are developers considering merging mantaflow into blender for 2.80 release? If not, I think these bugs should be addressed. As it is, we have a broken simulation system that should not be shipping with an official release.
I have also recently noticed this. I'm working on a mixed platform pipeline to which I introduced blender. The acceptance has been good and people are excited about what blender can do. That said, not everyone is going to change overnight to blender. And for the time being I still have to export the final scenes (and simulations) to be rendered in Arnold. Not having a correct naming structure is causing several problems with the workflow and being able to sell the team on blender's capabilities.
I have also noticed this recently. I simple fix could be to have the index before the frame number. i.e: fileName_index_frameNumber

You are correct. It is possible to bring it from 2.79. That's what I'm doing now, but it's a much slower (and limited) workflow.

Any news on this? I'm also working on a simulation that requires subframe sampling and it would be great for this to work.
