regl ScatterGL points disappear during selection selection with large number of points

[jonmmease]

First off, the new regl-based scattergl is awesome. Thanks @dfcreative and @etpinard

Description

When I create a scattergl plot with 20k+ points, the points disappear during a selection operation (both lasso and box select). After double clicking to exit the selection mode the points re-appear. In the console, I see the following error.

4VM7119:2 Uncaught TypeError: Cannot read property '222' of undefined

Things work fine when I test with around 10k points.

@jmmease thank you! Will be fixed with #2267

I have this same problem, but without any error. This is ~30,000 points. When I plotted less than 10,000.

Details
Plotly 1.37.1 from npm
Chrome Version 66.0.3359.139

Should I create a new issue?

Thanks for reporting this.

Should I create a new issue?

If you could isolate the problem in a codepen/jsfiddle/jsbin with just your data/layout graph - it would help us immensely.

Here is a plot using my data: https://codepen.io/meganrm/pen/odKveW

Both box select and lasso select make all the points go away. I haven't tested to see if the callback still gets the points or not. And I don't see any errors.

Thanks very much for the codepen. @meganrm

It's a separate issue. Your graph appears to work fine w/o the transforms array. You can subscribe to #2671 for the most up-to-date development info.
