IDEX XY Offset drift (VC4)

My Vcore 4 prints well so far. But while printing a large multi-colour model, I noticed a problem. My XY offset drifts on higher models. While it is perfect on the lower part of the print, it drifts more and more until (in this case) it overextrudes areas and the toolhead loses steps when hitting it.
At first I thought it was some sort of thermal expansion etc, but this happened when printing PLA with all the panels off.
Any ideas? I'll do some more testing tomorrow.
