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
