Steps to reproduce:
1. Open project attached by QA
2. Open 'Scene1_Intro' scene
3. Select 'Main Camera' and make sure unnecessary shaders/effects are deselected (Might've reset during reopening. This lowers build time). Screenshot attached
4. Deploy to device
5. Tap on the screen to enable full-screen effects

Expected results: A light bloom and blur effects are applied
Actual results: Screen majorly blurred
