I discovered this when playing on Rip Rip Rip's new Portal 1 Chamber 11 recreation that he posted in #beta-maps-share, though I wouldn't see why not this would happen in any other map with deadly water.
To Reproduce
Just jump into deadly water and let the game load a save from death.
Describe the bug
When dying in water, the aquatic overlay that appears on the screen when underwater continues to exist after loading a save from death. Here's a video of it in action. https://github.com/StrataSource/Portal-2-Community-Edition/assets/69723642/7a5d7518-d709-4984-86c8-46bcbbdbecbb
