WebGL is not working as well in js api 4.8. WARNING: Too many active WebGL contexts. Oldest context will be lost.

Hi.

I use js api 4.8 and arcgis server 10.6.1. I use FeatureLayer with enebled WebGL. I have a problem when turn on  many layers , more than 50 . 

and get WARNING: Too many active WebGL contexts. Oldest context will be lost./  

And some layers desappere. Once it happens i get some other errors

So question, is there limit of WebGL context ? Is there any way to fix this issue?

Thank you

I've seen this too. I think it was 8 or something. It really hammers then bombs Chrome.  I was hoping first vector tiles would be my savior to slowly loading layers in viewers. (with fast servers, lots of memory and coming from fgdb and 10.6.1 etc). However since they don't have popups and full attributes to query, those can't replace map image dynamic layers. I then saw web GL presented this year at dev conf. But I have also run into this issue. Between this, security issues and minimal backward compatibility it would seem these are not a full replacement yet either. I just need my layers to draw faster. Will keep researching.  And perhaps at some point web GL will be the way forward, as hardware continues to modernize and various caveats such as security and performance limits are worked out with web GL. But yes I have seen this issue too. It alone made it a non-starter, as it bombs the browser or at a minimum the tab.
