Delta printer surface artifacts

Hi, I noticed my Delta having surface artifacts. This happened after I uploaded a new Marlin to it (2.0.5.4) half a year ago.

What could it be and how can I troubleshoot this? The prints come out fine but these artifacts appear on all vertical walls all around. There is no play but I do feel as if the machine also makes more of a grindy noise on some moves. Can it be an issue of stepper motor/driver combo?

It uses Skr 1.3, tmc2208 on 12v. Everything works great, prints come out perfectly.

Moving this to Delta as it might be a specific issue.

Hmmm that really looks like the same issue that was discussed in this thread [reprap.org] but you have TMC drivers so it seems like they shouldn't be that bad. When you upgraded to Marlin 2.0.5.4 did you also upgrade your controller? Anything change in your config file when you updated? What version of Marlin did you upgrade from? What microstepping do you have your TMC drivers set to?
