WebGL is not working

[HADB]

WebGL is not working in v1.5.0

[David-Desmaisons]

Could you create a project with a minimal set-up with this problem, so I can investigate?
Thanks.

[HADB]

OK, I will give you next week.
PS: I'm trying to show a web page in iframe which using WebGL and tells me WebGL not working.

Meanwhile try to check the log and verify if you need to set a CEFswitch

Hi, I have set up a minimal project https://github.com/HADB/Neutronium.Vue.SPA.WebGL

What I have done:

1. Create a project with Neutronium.Vue.SPA template
2. Edit View/src/main.vue, add an iframe element which contains a WebGL sample source

<template>
    <main>
      <v-content>
        <v-container fluid class="main-container">
          <iframe src="https://webglsamples.org/aquarium/aquarium.html" />
        </v-container>
      </v-content>
    </main>
</template>

<style>
...
iframe{
  width: 100%;
  height: 100%;
}
...
</style>

3. Build and run

Screenshots:

1. The WebGL sample in chrome
   
2. Result in Neutronium app
   

I have got these logs in bin/Debug/debug.log

Maybe this is related to the following line but I didn't test because I couldn't find a way to remove this CEFswitch.

Neutronium/WebBrowserEngine/ChromiumFX/HTMEngine.ChromiumFX/ChromiumFxWebBrowserApp.cs

Line 23 in 8603928

commandLine.AppendSwitch("disable-gpu");

[David-Desmaisons]

It seems that this is linked to this switch indeed, I can add a way to not call this switch although this might cause other problem in the display.

[David-Desmaisons]

@HADB I will provide in version 1.5.1 a way to not disable Gpu. On ChromiumFxWebBrowserApp:

        /// <summary>
        /// Set to true to allow Gpu
        /// </summary>
        protected virtual bool AllowGpu => false;

I remember that the past using GPU could introduce some bugs in display so by default Gpu will continue to be disabled.

[David-Desmaisons]

Available in version 1.5.2

[HADB]

Problem solved. Thanks!
