Glowing effect creates ghost

[SlimeDog]

Spigot 1.12.2
OptiFine 1.12.2-HD-U-C8

/effect {playerName} minecraft:glowing 100 1

renders the player as a ghost.

It correctly creates the "outline" aura without OptiFine.

Options > Video Settings > Performace > Fast Render:OFF masks the ghosting.

I believe this is intentional as it butchers the frame rate on lower end computers. Or it could be a bug.

On my higher-end computer...it's not a feature. :)

The spectral effect (glowing outline) is not compatible with Fast Render and with shaders. When one of them is active an alternative "ghost" effect is used instead.
