### Summary

Using splitscreen local coop and having extreme visual glitches and issues which completely break projects. This happens when you set the antialiasing to FXAA and have any post process/ camera blur setting enabled with splitscreen.  
Here’s a thread I’ve made about it on the forum for videos and evidence!

### What Type of Bug are you experiencing?

Rendering (Graphics / Niagara)

### Steps to Reproduce

Make a splitscreen project  
Add any kind of camera effects/background blur  
Turn antialiasing to FXAA  
Player 2’s screen ghosts player 1’s while also glitching heavily with flashing and bright lights.

### Expected Result

For both players to have regular views and background blur on FXAA without screen flashes and glitches.

### Observed Result

Player 1’s screen is fine, player 2’s (on right half of the splitscreen) the screen ghosts player 1’s screen as well as had insane flashing lights and visual errors.
