This happened in every beta version of TM2 in Catalina/Mojave/High Sierra/High Sierra/Yosemite with even few hundred of lines. 

Not always but it did happen 

1. while scrolling, some text at bottom of TM window may overlap others, continue scrolling up/down will clear the mess.

2. when using cmd+s search, after located the line, Esc to cancel bottom search bar, the mess might appear 

3. when using cmd+s search, deleted some lines from visible area, continue scrolling down or cmd+s will get this mess.

Sent from my mobile. Ignore the typos unless they're funny.

I am not sure that it has anything to do with large files.

From the reports, it sounds more like a macOS 10.15 issue.

Is anyone not on macOS 10.15 seeing this?

The gutter and main text are actually two different scroll views with different code, the former being much simpler, so seeing gutter is also affected by this issue, it very much sounds like a bug that only Apple can fix.
