Block marker particle causes lag when viewed up close when fullscreen is enabled

The bug

Looking closely at block_marker particles created with a repeating command block can cause lag if fullscreen is on.

How to reproduce

  1. Use this command to create a repeating command block that will generate the particle:

    /setblock ~ ~-1 ~ repeating_command_block{Command:"particle block_marker{block_state:\"minecraft:stone\"} ~ ~2 ~ 0 0 0 0 0 force",auto:1b} replace
  1. Open the debug screen with the Frame time graph (Alt + F3)

  2. Turn on fullscreen (F11)

  3. Get as close as you can to the particle an then move away
    ❌ See if your fps drops as you get closer

  4. Turn off fullscreen (F11 again) and repeat step 4
