Yes also broken UI for me, plus there is a long-standing color-map
defect in XPaint where some images lose original content.

Another idea besides a GUI program would be the Netpbm command line
suite, also in pkgsrc. Sometimes the manual page examples are
insufficient, but I did find a good hint on stackoverflow, herein
snipped from a quick test I ran:

CANVAS_W=4800; CANVAS_H=3450; W=1000; H=1000; x1=500; x2=500
ppmmake blue "${W}" "${H}" > overlay_img.pnm
ppmlabel -x 50 -y 50 -text hello -angle -30 -text there
overlay_img.pnm > overlay_img+text.pnm
ppmmake red "${CANVAS_W}" "${CANVAS_H}" |\
  pamcomp -xoff="${x1}" -yoff="${y1}" "overlay_img+text.pnm" - |\
  pamtopng -transparent=red  > final.png

Also see "pbmtext - render text into a PBM image".
