While playing in a world with RTX on, I noticed that all the signs were empty. Then, I turned RTX off and I could see all the text in them. I'm using Vanilla RTX Normals.
This started happening in 1.19.70.24 Preview.
I think this is related to MCPE-167551.
Steps to Reproduce:
Write something in a sign.
Turn RTX on.
Observed Results:
The sign text isn't visible with RTX on.
Expected Results:
The sign text is visible with RTX on.
Texture pack glitch most likely, I used Defined PBR and I can see sign text.
