Oh, thanks for reminding me to check this one! Unfortunately, it looks like it got more complicated. In both 2.83.2 and 2.9 Alpha (f319eec88186), the bug is gone when it's simulated using Replay type cache (though with several glitches before the first keyframe, probably related to caching). But when it's simulated in Modular or Final/All, the bug is still there. The color changes won't be visible in the viewport, but, if rendered in Cycles, the whole plume of smoke changes color at once, instead of just the newly emitted smoke.

For some reason, in the newest build of 2.9, the simulation isn't at all visible after baking the noise, so I tried this on a previous build instead: 2.90 - c8060a78fdf3 . And, yes, unfortunately the issues persist.
The smoke moved a lot slower in 2.9, so I ended-up using a wind force-field to really accelerate it.
By the way, these issues were also present in 2.82.0

@Everton Schneider (eversimo) You're right, 2.90 alpha seems to have the issue fixed with force fields. If smoke/flame Vorticity are the only properties influenced by this bug, it's probably not significant anymore, in my opinion. So, I'm glad to see this pretty much resolved!

@Everton Schneider (eversimo) That's strange. I just tested in 2.83 50ef801a79b5, the issues still persist there.

An unqualified guess here, so please correct me if I'm wrong! But I suppose this might be due to Blender treating this as if no more pressure is being added to the smoke. So, despite the insistence of even velocity, the smoke can't expand properly. However, due to the constant emission of new particles or the fact that Flow Behavior is set to Inflow, I believe it follows that more pressure should be added over time.

My apologies. I forgot to include the fact that "unborn" and "Dead" need to be disabled in the Particle Instance modifier. I have tested this with the newest version of 2.79 and it seems to be working just as fine as the previous versions. In the recent builds of 2.8, however, it doesn't work properly.
