This bug is a graphical glitch or error
Describe the issue
The part of a flat-to-steep track piece that should be visible in a tunnel entrance is not rendered:
It is however temporarily rendered if the virtual floor from building something else is touching it:
This reminds me a bit of rendering changes triggered by the virtual floor as in #22054
Steps to reproduce
- start a tunnel with a flat-to-steep track piece
- track not rendered in tunnel entrance
