-

Mar 31, 2023

How to reproduce:
1. Open the attached user project “TMPTextBug.zip“
2. Open Scene “Sample_03_TextStyleAssigner”
3. Zoom on to the bottom of the text in the Scene view

Expected result: The text doesn’t disappear
Actual result: The text disappears

Reproducible with: 3.2.0-pre.3, 3.2.0-pre.4 (2020.3.46f1, 2021.3.22f1, 2022.2.12f1, 2023.1.0b9, 2023.2.0a8), 4.0.0-pre.2 (2022.2.12f1, 2023.1.0b9, 2023.2.0a8)

Reproduced on: macOS 13.0.1 (Intel), Windows 10 (by reporter)

Note:
- Not reproducible in Builds
- The mesh renderer of parent and sub-mesh are disabled
- Frustum is based on the bounds of the parent and doesn’t include the sub-mesh bounds, it’s a problem because if there are only fallback’s characters, the parent’s bounds will have a size of zero and the text will always disappear
