PrincParshias Fullscreen Windowed Mod (1.21.11, 1.21.1) forces the game to run in a borderless fullscreen window instead of exclusive fullscreen. This makes tabbing in and out of the game smoother, prevents resolution changes, and improves compatibility with multi‑monitor setups. It’s a lightweight quality‑of‑life mod designed to make Minecraft behave more like modern PC games when switching between applications.

Features:

  • Runs Minecraft in borderless fullscreen window mode.
  • Eliminates screen flicker and resolution changes when alt‑tabbing.
  • Improves performance and stability on multi‑monitor setups.
  • Lightweight and simple, no extra configuration required.
