Only the software renderer is working

[baszczewski]

Whenever I try to run an animation with a renderer other than software, I encounter an error:

TypeError: Cannot read properties of undefined (reading 'resize')

Confirmed on the following browsers:

• Chromium 131

Firefox (v133) is also problematic, though in a different situation, and returns a different error:

Uncaught (in promise) TypeError: this._TVG is undefined

@baszczewski
I just tested on my chrome(v131), it works well.

Still not sure, I assume the WASM binary from the network isn't fetched properly. Could you please capture network tab on developer tools as well?

[baszczewski]

Sure. I prepared a short video to show the debugger's behavior at different stages of the application's execution. I should also mention that I don't have any adblockers or other scripts in the browser that could affect the functionality of the page.

Maybe the error is due to the application always trying to create a WebGPU context, even when I choose WebGL?

@baszczewski May I ask your OS and graphics device?
@tinyjin Just so you now, firefox (v133) with WebGL/WebGPU doesn't work on my Windows machine as well. Edge/Chrome nicely work.

When using WebGL:

@baszczewski
I think your chromium's gpu feature flag option turned off. Could you go to chrome://gpu/ and check whether webgl/webgpu are available?

[tinyjin]

@hermet Yes, I found firefox/safari browsers don't run WebGPU as a default option. I'll support feature checker so library doesn't break and notice users.

@tinyjin May I ask what is the default option? I can test many WebGPU samples on firefox. More problem is our viewer doesn't work with WebGL as well.

[tinyjin]

WebGPU support used to be on experimental option, users had to enable the option. Now chrome(chromium) gets this default enabled from 113 version.

While chrome does, Firefox/Safari still doesn't support WebGPU as default, which means users should enable by them selves.

I also had same issue that our WebGL2 doesn't work in firefox. Still unknown, I will investigate it : )

[tinyjin]

In thorvg.web lottie-player, WebGPU initialization wrongly called even in WebGL case by logic bug.
As a result, WebGL didn't work when WebGPU feature isn't supported.

Corrected this, thorvg/thorvg.web#87

@baszczewski May I ask your OS and graphics device?

Sure. On a daily basis, I work on Fedora 39 (Linux) using up-to-date open-source graphics drivers. My graphics card is a Radeon RX 6600, which, as far as I know, supports the latest versions of OpenGL and Vulkan with these drivers. Unfortunately, I’m traveling at the moment, so I can’t provide more detailed information.

I experienced viewer issues with this setup on various browsers, including Chromium and Firefox.
