When minimizing the Minecraft window on Windows 10, anti-aliasing will be disabled temporarily upon bringing the window back up. Adjusting the anti-aliasing slider in settings will re-enable it.
Steps to reproduce:
-Enable anti-aliasing in video settings (preferrably x16 for a more noticeable difference)
-Minimize the Minecraft window (minus symbol on the top right corner)
-Bring the Minecraft window back up.
Anti-aliasing remains active, providing a more visually pleasing experience.
Anti-aliasing disables, leaving edges looking rough.
Refer to the attached images for a visual representation. There is no difference between anti-aliasing set to x1 and anti-aliasing set to x16 after minimizing the game window.
