### Godot version

v4.1.1.stable.official [bd6af8e0e]

### System information

Godot v4.1.1.stable - Gentoo 2.14 - Vulkan (Compatibility) - AMD Radeon Vega 8 Graphics (raven, LLVM 16.0.6, DRM 3.49, 6.1.41-gentoo-x86_64) () - AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx (8 Threads)

### Issue description

This minimal project crashes when run with the background TextRect visible, but if you toggle its visibility, no crash occurs. Note that this only started when I scaled down the TileMap to half (either by scaling MapCenter or Dungeon).
