Firefox WebGL warning (Alpha-premult and y-flip are deprecated for non-DOM-Element uploads).

[jwoodwardtfx]

When running in Firefox we get the following warning:
WebGL warning: texImage: Alpha-premult and y-flip are deprecated for non-DOM-Element uploads.

Google shows up the following:
https://bugzilla.mozilla.org/show_bug.cgi?id=1400077
mapbox/mapbox-gl-js#5292

Is this an issue or a performance limitation we should be concerned about (as the Firefox developers say this path isn't optimized and should not be used)?

Since the issue is known at least from 2017, vide mapbox/mapbox-gl-js#5292 is there any plan to fix/workaround/address this problem?

Can you please share a reproduction of this issue?
Generally speaking, Firefox has a very low usage statistics when it comes to browsers, but if someone would like to invest in fixing this, please do.
If this is a performance concern I might be able to assign a bounty to it, but I'll need a clear reproduction example first

You can just open this page in Firefox https://maplibre.org/maplibre-gl-js-docs/example/simple-map/ and look into the console.

I'm using Firefox 110.0 (64-bit) on Ubuntu

Would you be interested in working on this issue?

Thanks for the info!

@HarelM I'm not even an user yet ;-) - just investigating future possibilities for the integration and that was the first "warning" to see the known issue opened since 2017 without addressing.

I can have a look at this.

I'm having a look at the code paths triggering the warnings, and am currently considering skipping the creation of textures when the atlases are empty. This won't get rid of all the warnings, but it should avoid telling the GPU to allocate 1x1 px textures needlessly.

Would be very nice if you could push this forward. Let me know if you would like me to assign this issue to you.
