Confirmed.

So I changed the setting of org-preview-latex-process-alist

To 

((dvipng :programs
         ("latexmk" "dvipng")
         :description "dvi > png" :message "you need to install the programs: latex and dvipng." :image-input-type "dvi" :image-output-type "png" :image-size-adjust
         (1.0 . 1.0)
         :latex-compiler
         ("latexmk  -f -pdf -output-directory=%o %f")
         :image-converter
         ("dvipng -D %D -T tight -o %O %f")
         :transparent-image-converter
         ("dvipng -D %D -T tight -bg Transparent -o %O %f"))
 (dvisvgm :programs
          ("latex" "dvisvgm")
          :description "dvi > svg" :message "you need to install the programs: latex and dvisvgm." :image-input-type "dvi" :image-output-type "svg" :image-size-adjust
          (1.7 . 1.5)
          :latex-compiler
          ("latex -interaction nonstopmode -output-directory %o %f")
          :image-converter
          ("dvisvgm %f --no-fonts --exact-bbox --scale=%S --output=%O"))
 (imagemagick :programs
              ("latexmk" "convert")
              :description "pdf > png" :message "you need to install the programs: latex and imagemagick." :image-input-type "pdf" :image-output-type "png" :image-size-adjust
              (1.0 . 1.0)
              :latex-compiler
              ("pdflatex -interaction nonstopmode -output-directory %o %f")
              :image-converter
              ("convert -density %D -trim -antialias %f -quality 100 %O")))


But now I receive
