[Chrome OS] WebGL error - RENDER WARNING: there is no texture bound to the unit 0

Description
As soon as our participant start using our application (and so the Web SDK) to do meetings, tons of error (logs) start to appear.
The participants are using Chrome OS and Chrome Browser, and the mentioned logs can be found below.

This seems to be related to your code, or the data you send (empty texture) - i’m not an expert so please verify that with your engineers, you can find a description of how to fix it here

Not sure if it has a negative impact on rendering performances, but it’s definitely better to clean such error messages.

Hey @nvivot,

Thank you for reporting this, I’ve reached out to our engineering team for their guidance. (ZOOM-283727)

Thanks,

Hi Max,

Are there any news on that topic ?

@nvivot

No update so far but I’ve reached back out to learn the status.

I’ll let you know what I hear.

Max

Ok, thanks.

I have no idea whether this could cause anything on a chrome OS. We have a couple of regular crashes from people using these chrome box, and these tons of logs every few milliseconds are probably not a good sign.

Hope your team will find some time to investigate on.

Regards,
Nicolas.

@nvivot

I haven’t been able to narrow this down myself either. I’m hoping we’ll be able to get to the bottom of this too.

@nvivot

Our team got back to me and indicated that this should have since been resolved. Please test with v1.9.7 to confirm that this issue was fixed.

Max

Hi Max,

We are going to release the 1.9.7 on production next week. I’ll chek after that if we still see this kind of traces on the chrome boxes.

Thanks.

Sounds good, thank you!

Max

Hello Max,

Unfortunately I can confirm this error with freezing video in version 1.9.8. The video in speaker view stops with a lot message of this error. Only switching to gallery view and back resolves the freeze.

Best,
Andre

Hey @andresavic,

Thank you for reporting this. First, please confirm that you have implemented Web Isolation along with the WebCodecs and SIMD Origin Trials referenced there. Then, please provide the version of Chrome that you’re using.

Let me know if that helps.

Thanks,
Max
