    We are sometimes seeing native crashes when using the Painter2D API and hitting the 65535 vertex limit. Is this a known issue? We also have crash & exception reporting enabled in our project, but these crashes are not being reported :(

    We have already done some work to simplify the shapes we're drawing in this case, but since there is no way to detect when we are approaching the 65535 limit I'm not sure what else we should be doing to avoid this issue.

    The crash below occurred in a standalone build on an M1 Mac.

    Code (CSharp):
    1. A VisualElement must not allocate more than 65535 vertices.
    2. A VisualElement must not allocate more than 65535 vertices.

    This is not a known issue. Can you please report the bug with the bug reporter tool (Help > Report a Bug...) from your project, and we'll have a look.

    Yes, it can be difficult to know when the limit will be reached. Don't forget that the limit is per-VisualElement, so one way to increase your limit is to split the shapes into multiple VisualElements.

    This is something we considered, but we'd still just be guessing when to split into a new element. We are trying to produce real-time data plots from time series data. We thought he had a decent workaround until now by limiting how close adjacent points could be (e.g. never appending points less than 2 pixels apart), which seemed to keep us under the vertex limit in testing, but a user seems to have found a way to get over the limit after all, haha. In the past this just resulted in an empty VE, though, rather than a crash.

    That's definitely what is expected to happen.

    We may be able to relax the vertex limit in the future, but probably only in Unity 2023.2+.
