Original Pull Request: https://github.com/microsoft/terminal/pull/5149

State: closed
Merged: Yes

There are two antialias modes that can be set on the ID2D1RenderTarget:

  • one for text/glyph drawing [1]
  • one for everything else [2]
    We had to configure that in the RenderTarget.

Additionally, when clipping the background color rect, we need to make
sure that's aliased too. [3]
