Not a `MOZ_ASSERT`. From the log above:

```
/usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/12.2.1/../../../../include/c++/12.2.1/bits/stl_vector.h:1123:
  std::vector::reference
  std::vector<mozilla::wr::RenderTextureHostSWGL::PlaneInfo>::operator[](std::vector::size_type) [
    _Tp = mozilla::wr::RenderTextureHostSWGL::PlaneInfo,
    _Alloc = std::allocator<mozilla::wr::RenderTextureHostSWGL::PlaneInfo>
  ]: Assertion '__n < this->size()' failed.
```

This is an out-of-bounds access on a `std::vector` with item type `mozilla::wr::RenderTextureHostSWGL::PlaneInfo`.

  ]: Assertion '__n < this->size()' failed.
```

This is an out-of-bounds access on a `std::vector` with item type `mozilla::wr::RenderTextureHostSWGL::PlaneInfo`.

PS: My guess is either `mPlanes` vector is being mutated concurrently and it asserts on line 178, or the vector has size 0 and it asserts on line 200.
