Ahhh! That explains a thing or two. I didn’t realise that @blocking 2 didn’t manage the buffer sizes. That helps me understand why @blocking 1 is causing a little hiccup in the constant graphic drawing i’m doing in my patch. Ironically @blocking 0 gives me the worst hiccuping.
In this circumstance I think I can get away with @blocking 1 as it only seems to pause the graphic drawing on the first call for processing.
