Error: Framebuffer status: Incomplete Attachment

Hello,

I am facing this error: Error: Framebuffer status: Incomplete Attachment when I enable webGL context on Canvas (with 2D context it works fine). I am using the Phaser v3.80.0.

It also all works fine in the Chrome browser, but I am testing it on a set-top box.

Here are the console logs:

I would like to know what is possible root cause of that issue so I can try to fix that.

Thanks a lot for any help
