Original Pull Request: https://github.com/microsoft/terminal/pull/14193

State: closed
Merged: Yes


If the opacity is set to 100%, the background becomes solid instead of 'fully opaque acrylic'. If the opacity is below 100% the acrylic material is re-enabled (depending on the user's settings).

Validation Steps Performed

I updated two unit tests to reflect the change in behavior and manually tested the transition from <100% opacity to 100% opacity (and vice versa) on win11.

Steps:

  1. Start with 100% opacity and acrylic material enabled.
  2. Decrease opacity and observe acrylic effect.
  3. Increase opacity back to 100% and disable the acrylic effect.
  4. Decrease opacity and notice that acrylic effect is no longer there.

Closes #12880
