Why the background texture and color changes when exporting?
This is the original image I want to export. The file is in RGB

But when I choose Save For Web/PNG/JPEG it all turns out like this

It ONLY works when I export it using Save For Screen with this exact settings

But I dont like using Save For Screen method because sometimes my images always get jittered like this when exporting, I also doesn't know what causes this..

This is my color settings

Anyone can help me find the cause and how to fix this?
