good morning,
i have a Phrozen Sonic Mighty 4K
I have noticed this problem on prints (object and supports)
the defect is clearly visible on the supports,
seems a shift and then fell back into place,
in addition when it does this defect the layer seems even bigger,
resembles the effect of a flush FFF print
