    Hello everybody,

    I recently updated to 2018.1, using the new PostProcessing and the Light Rendering Pipeline.

    I encountered a weird issue that when I zoom out, the performance suddenly drops and the memory consumption goes up.

    According to the profiler the reason are my tilemaps. However this even happens when my tilemaps are empty and I have no animated ones. I could also not observe that RefreshTiles, GetTileData or GetTileAnimationData are called. Which makes sense since there are no tiles present.

    When I disable the TilemapRenderers the issue does not occur. However in the moment I turn it on, the performance drops and the memory consumption goes up.

    This issue is completely new and only happens since I upgraded to 2018. It is often so severe I have to use the task manager to kill Unity.

    Did anyone observe a similar behaviour?

    Thanks,
    Daniel

    This seems to be an issue of the Light Rendering Pipeline. When I disable it and revert to the default rendering, the issue seems to be gone.
