Is the DS18B20 missing "rapid changes" or is the SHT30 spewing inaccurate readings? A 2 degree spike from one minute to the next is possible, but it looks suspiciously like a bad/jittery sensor. Especially so for a sensor that claims 0.2c accuracy.

I wonder. In the couple days after this screencap the DS18B20 also had some weird spots where it jumped up above the SHT30, paralleled it for a while, and then dropped back down. So I'm inclined to treat it as a bit flaky, though for rough comparisons/tracking still useful (especially since it's cheap and 1-wire is easy to hook up).
