An option to turn off the smart scroll feature was included in one of the recent updates (probably in the March 2020 update, I didn’t find it in the changelog), see more: issue #69480
Since then, I’ve been able to “save” the scroll state, try this:
- Go to File > Preferences > Settings (or Ctrl + ,)
- In Features > Output, disable Smart Scroll option (or search output.smartScroll.enabled)
Tested with VSCode version 1.45.1 and CodeRunner 0.10.0
