Why Is My Screen Gray, Wavy or Pulsing? Identifying Canvas Screen Effects

Sudden visual changes during play are often a Canvas effect that another mod or a server command has triggered. These effects fade in and out smoothly, and some come as short pulses that respond to events. Knowing which effect you are seeing lets you decide whether to keep it.

Match what you see to the effect

• The world loses its color: *Desaturate*, used for gloomy or dramatic scenes.
• Colors split into red and blue fringes near the edges: *Chromatic Aberration*.
• The screen edges go dark: *Vignette*, which draws your focus to the center.
• The whole view ripples or waves: *Wobble*.
• The effect throbs rhythmically, often at low health: *Heartbeat*, which pulses with low health or action events.
• Soft blurring or a grainy texture: *Blur* or *Film grain*.

What to do about it

1. Check your health and surroundings first. Heartbeat and similar pulses are often meant as warnings. Healing up may make them fade.

2. On a server: Effects can be triggered from server commands, so a server event may be the cause. Ask the server staff if you are not sure.

3. To reduce or disable an effect: Open the Canvas settings screen from your mod list. Lower the effect's strength or switch that filter off.

4. If the effect never fades: Leave the world and rejoin to clear it. If it keeps coming back, turn it off in the settings screen.
