Bug when spawning water planes manually with TAA enabled

[66OJ66]

Hi, I've encountered a rather obscure bug when experimenting with spawning WaterTiles manually in my game.

In short, if a WaterTile is spawned after startup and the camera has TAA added (TemporalAntiAliasBundle), the water shader doesn't work correctly.

I've uploaded an example repo here which has 3 modes:

enum Mode {
    /// Use bevy_water's default plugin so water spawns automatically. TAA enabled.
    WaterPlugin,
    /// Press 'E' to spawn water manually. TAA disabled.
    ManualSpawnNoTAA,
    /// Press 'E' to spawn water manually. TAA enabled.
    ManualSpawnTAA,
}

These look as follows:

Mode::WaterPlugin

Mode::ManualSpawnNoTAA

Mode::ManualSpawnTAA

Sorry I don't know why that happens. I tested your code locally and it happens like you said. Also I updated the code to Bevy 0.15 (doesn't happen here) and Bevy 0.18 (happens here too). Maybe there is a timing issue. I don't think this is caused by a bug in bevy_water.
