Sorry, failed to mention that I am running python 3.9.1 from python.org
Perhaps you should notify https://anaconda.org/contact/report.
Quote:I use Windows 10 + anaconda.
But as I said previous that when use python3.6 is OK, just as what your screenshot shows. but while use python 3.7 or later version, the effects gone!
Perhaps you should notify https://anaconda.org/contact/report.
