i made myself a CRT material but due to the high fequent color changes TXAA ends up making pixels purple. im using a chamera fade for the effect so that fixes most of the problems with it however the problem still persists when looking at it from the side: http://i.imgur.com/xj8sKMI.png and without AA: http://i.imgur.com/tVnPb0W.png
whats the best way to get rid of this purple issue without disabling TXAA?
