The first message ("Ignoring ...") is written with fprintf(stderr, ...). The second message ("Font not found") is written with fputs(..., stderr). Without specific mintty configuration, reproducible with the command (parentheses needed): (mintty --fn "dummyfont" -o dummyopt=none&) Observable with 3.1.0, 3.1.2 or snapshot 2020-01-31. Sorry, I could not reduce the test case to a simpler setup.
