Hi @jerrify ! The immediate problem looks to be a bug related to terminal color detection. Your report is great and gives enough information to fix it, which I’ll get started on.

Until then, you could try running with a different terminal emulation that supports colors. If you’re still running into difficulty, what is the output of echo $TERM;tput colors ?
