Screen issue

[KingRCooper]

Hey, I recently updated my project from 4.8.3 to 4.9.2, and everything is fine except that now my play screen has what looks like dirt around the edges. I have 2 maps, a main menu screen and the main play screen, the menu screen doesn’t have this problem. Anyone know why it’s doing this? Thanks

check your post process blendable materials, they have changed one node, i don’t exactly remember which one, but there are would be error message with new node name.
