Water seems extremely foggy when entering it with night vision, much more so than in 1.16.5. Water in general seems to be much more foggy than in 1.16.5, but with night vision it makes it much more noticeable.

Note that I play on a fairly large display near myself, so I have the FOV turned up to 80. With the default FOV it appears slightly worse than in the screenshot.
The first screenshot is with night vision, and the second is without. Note that it appears backwards.
