When changing the video settings, the game updates these settings as soon as the button is pressed:

• Graphics
• Smooth Lighting
• 3D Anaglyph (this also reloads the resources)
• GUI Scale
• Clouds
• Fullscreen
• Mipmap Levels (this also reloads the resources)
• VBOs
• Render Distance
• Max Framerate
• View Bobbing
• V-Sync
• Alternate Blocks
• Language (not a video setting, but is similar to one)

These settings do NOT update until the game is resumed:

• Brightness
• Particles
• Resource Packs (update when pressing "Done")

The settings should either all update live or all update only when the game is resumed. Ideally video settings should not be live-updating.
