As you might know, when you press F4 while spectating a mob with a shader effect it will toggle the shader effect on and off. But because the game mode switcher is opened using F3 + F4 you will also toggle that effect at the same time. This is inconsistent with other F3 shortcuts, for example F3+ D or F3 + A don’t perfrom the action done by pressing these buttons, so you don’t move, but this is not the case for F4. Discovered while testing MC-46503.
- Spawn a creeper, enderman, spider or cave spider
- Go into spectator mode
- Spectate the mob
- Open the game mode switcher by pressing F3+ F4 (I would recomment to move the cursor to spectator mode before closing the game mode switcher to prevent you from stopping spectating the entity)
The shader effect gets disabled. If you do it again, it will be enabled again.
