Summary

  • add an opt-in frontend MSAA setting with disabled, 2x, and 4x modes
  • apply the selected MSAA level during desktop OpenGL context creation
  • add a --anti-aliasing command-line override

Why

Some virtual display / streaming setups flicker in the frontend. ES-DE exposes this setting and documents 2x MSAA as a workaround for severe frontend flickering on buggy Windows GPU drivers; RetroBat did not expose an equivalent setting.

Validation

  • git diff --check
  • cmake -S . -B build fails locally because the FreeImage development package is not installed
