C2XC1211 x Secured Borders. White seedling with green stripes. The only one like this is HPSXSB231 and HPS is a kid of C2XC1212 (a sibling of C2XC1211). Started going green after a month.
Hypothesis: broken color blooms create higher chances of seeing variegated leaves.
This is not the only example I saw this year.
