Windows Terminal version

1.18.1421.0

Windows build number

10.0.19045.2965

Other Software

oh-my-posh v16.8.0
Ubuntu 22.04.02 LTS

Steps to reproduce

  • Make sure oh-my-posh is started automatically on startup
  • Open a new tab
  • Notice the render problems
  • Press enters, type text
  • Notice even more render problems
  • Wait a while and see the renderer catch up

It seems impossible to create a screenshot with the snipping tool because when the focus on WT is lost, the renderer catches up immediately.

Tearing of a tab created an error the very first time, but couldn't reproduce it anymore.

Expected Behavior

No response

Actual Behavior

Various rendering issues
