Scroll happens line by line
- iTerm2 version: 3.3.9 and all checked older versions
- OS version: 10.15.3
Detailed steps to reproduce the problem:
- Open iTerm2 and run some command that produces many lines of output, e.g.
for i in {1..1000}; do echo $i; done
- Scroll up with the trackpad.
What happened: Screen scrolls line by line.
What should have happened: Smooth continuous scrolling.
I remember that a few years ago the scrolling was smooth, and then at some point it switched to line-by-line for me. I thought I messed up some setting and in the end decided to reinstall iTerm2 cleanly. I deleted the application, ran
defaults delete com.googlecode.iterm2
and installed version 3.3.9 from the website. Unfortunately, this hasn't solved the issue. I also checked numerous older versions, back to 2.0, deleting the settings each time. All of them scroll line by line. Toggling GPU renderer in 3.3.9 has no impact either. I use relatively old hardware: MacBook Air 13-inch Mid 2012.
I'm attaching a debug log (tar.gz) from a clean installation of 3.3.9.
