White and black filter underwater

I found out there was a new update this morning which added various features, I did the update and decided to build a nether castle in the nether on a "Old" world, I got bored and was flying around using my elytra I flew into the water on accident to find out the whole thing was white and black, black for the void and white for the blocks, I instantly screen recorded it and screenshot it so i could report it as a bug
