Description
Describe the bug
When a decal texture is placed over another texture, and the texture underneath has a height displacement, this shows through to the decal. Meaning things like posters or drains or vents that are used as decals in source engine games get mixed into the underlying textures like stones, making them look incorrect.
How do you reproduce the bug?
Load into hw_confession_1 and noclip into the office and observe the posters on the walls.
This also happens in many other cases.
What is the expected behavior?
The expected behavior would be that the decal texture masks out the displacement or displays over top of the displacement of whatever texture is underneath it.

Research direction
Start by loading hw_confession_1, nocliping into the office, and observing the posters on the walls. Investigate the runtime's decal and height-displacement handling; done means decals mask or render over the underlying displacement without showing it through.
