Description

You can find this information under Information/System Information

• RetroArch: [version/commit]
  1.14.0

Environment information

• OS: Windows 10

No source files, tests, or entry points are named. Reproduce this on RetroArch 1.14.0 for Windows 10 using a content-directory override, then trace how the screen resolution setting is saved and reloaded; done means 1366x768 remains selected after quitting and reopening with the same core and content directory.
