Texture replacing TF2 water does not work

[AshenCinders]

Describe the bug

When playing a map with TF2 textures such as Rush (without TF2 installed), the water will pop in and out of existence as well as anything behind it such as other geometry.
If you go near the water and move the camera, it will get smeared.

(I have not validated that the water texture is actually from TF2 but other textures are.)

How To Reproduce

1. Uninstall/Unmount TF2
2. Launch Rush (https://staging.momentum-mod.org/maps/rush)
3. Go to stage 2 (1 jump to it)
4. Move around and look at the water.

Issue Map

Rush

Expected Behavior

Not look like my graphics card is dying.

Operating System

Win11 but confirmed by Ennui on Linux that bug also occurs

This isn't affecting map porting is it? Unless it's blocking ports, doesn't seem worth blocking 0.10.0 unless it's a quick fix

[AshenCinders]

As stated it only occurs if you don't have TF2 installed. You can still play the map, it's just very unpleasant.
I don't think it should be blocking 0.10

Yeah all good, comment was directed at the fact it was added to the 0.10.0 board
