Serial Monitor contains garbage after upload

Development Tools IDE 2.x

This is what I see:

This only seems to happen right after an upload, only on a UNO, using IDE 2.0 RC5. But not after a reset or when I unplug and replug the USB.
While it means little functionally, it is cosmetically ugly.

I am seeing that sometimes on a 1.8.13 version of the IDE. I simply ignore it and add print few "/n" in my setup. I have also had it miss the first message. I simply assumed it was something with changing the programming baud rate to what you selected before the final message from programing was finished. This is based on what little bit I know ESP8266 programing via the IDE. Somebody that knows should correct me if I am wrong.

I only presented it with the hope that someone familiar with the operations there might recognize how to fix it, so it stays pretty.
It seems to only happen after an upload, perhaps a buffer need flushed before the Screen Monitor starts spitting out data.

Thanks for your report @weshowe!

I have submitted a formal bug report to the Arduino IDE developers:

If you have a GitHub account, you can subscribe to that issue to get notifications of any new developments related to this subject.
