[MC-112849] fboEnable: false causes a black screen when looking at a glowing entity

The bug

When fboEnable is set to false in options.txt and the glowing effect is being rendered (for example when a mob is hit by a spectral arrow), the screen becomes black.

How to reproduce

Go to options.txt and change fboEnable set to false
Run Minecraft and open a world
Use the following command:
```
/summon creeper ~ ~ ~ {Glowing:1,NoAI:1}
```
→ ❌ Your screen will turn black

Confirmed on Windows 10, GTX 1060, Minecraft 1.11 and 1.11.2

Relates to MC-89755 but probably not a duplicate as in this case there is also no GUI visible.

EDIT
Though I fixed it but I didn't,
(it is fixed when optifine is installed and fast render is set to ON, regardless of fboEnable)

Duplicate of MC-71750 - the glowing effect is implemented with a shader (and that shader isn't special compared to the shaders that are used when spectating mobs (creepers/spiders/endermen)). That issue is resolved as invalid because the fboEnable option was removed in Minecraft 18w44a (a 1.14 snapshot), so both it and this issue no longer apply to current versions.
