The test print I showed in the pictures is here: https://drive.google.com/open?id=1doV6srMX5rTykufwo9jgSxIBOiGrGZas
Printer config can be found here: https://pastebin.com/Zh8gesXR
I took a video of part of the test print with both firmware versions. The outer curves of the print are where the issue is most noticeable, like in the pictures I posted earlier. In the post-1.19.2 firmware video, you can see the printer move more slowly on those curves, with louder extruder jitter, compared to the 1.19.2 firmware.

The test prints in the videos turned out identically to the earlier pictures in terms of surface finish.
Edit: Is there any other info I can post that might be helpful?
