Just tried the example again and it looks like logging is enabled, which would indicate it’s not a release build. Do you have your own app-manifest or similar?
Edit: I think I found it. Sadly it seems that variants does not work as expected for wasm builds, I will fix this and it should be available in next release. Until then, as a workaround, you should be able to modify the output HTML file by adding this:
engine_arguments: ["--verify-graphics-calls=false"],
to the extra_params
object. More details here:
Added issue DEF-3604.
