Applying saturation effect to one object causes shader being applied to whole screen

[ghost]

So, not sure how best describe this, but after I tried using SaturationEffectComponent in game, shader is sometimes applied to whole screen, or maybe all objects, using parameters from the component which was created last.

You may see this in a test game I was making, called "LayerGame":

• run game
• observe the first room and remember how it looks like
• press Ctrl + 2 to commence transition into second room, which creates few objects with saturation component.
• room 2 is loaded asynchronously, and you may notice how room 1 suddenly has saturation effect applied on it.
• if transition was too fast, press Ctrl + 1 to return to previous room once in room 2. You will observe shader applied over whole room 1.
• note, even in room 2 there are background layers (one with "planets" and one with multiple "islands") which do not have this component on them, yet they are still affected by shader.

I tried to reproduce this in Demo Game, but for some reason could not achieve exactly same result. However, you may try following:

• apply Saturation effect to any random object in any room. For example, to the lamp posts in "Dars Room".
• now when running the game, you will see saturation effect being applied temporarily to the whole screen every time during room transition.
