When using server-side Razor Components, because of the server-side rendering mechanism, only the last drawing operation executed will appear to render on the client, overwriting all previous operations.
In the example code above, for example, drawing the triangles would appear to "erase" the black background drawn immediately before, leaving the canvas transparent. That will allow the automatic batching behavior to send calls in the most efficient manner possible, and avoid unnecessary performance impacts.
Methods which return values are never batched. Such methods may be called at any time, even after calling BeginBatchAsyncwithout interrupting the batching of other calls. NOTE The "overwriting" behavior of server-side code is unpredictable, and shouldn't be relied on as a feature. In low-performance situations calls can be batched automatically, even when you don't explicitly use BeginBatchAsync and EndBatchAsync. This package is not used by any popular GitHub repositories.
