Incorrect rendering with many subplots

Oof, I ought to understand that ‘edit post’ and ‘reply’ are not the same, please ignore my stupid edit history on the above post.

One more note - this issue doesnt seem to happen for graph_objs.Scatter, just graph_objs.Scattergl objects. I unfortunately can’t just switch to Scatter though because it’s order-of-magnitude slower for the quantity of data I’m trying to render.

I also just found this thread which suggests a limit on the number of GL instances in a window: ScatterGL markers not displaying
However, if I’m understanding correctly, it seems that what I’m doing shouldnt hit that limit since they’re subplots and therefore part of the same GL instance? @chriddyp am I interpreting that correctly?
