How to add WebGL support to our app?

We tried to use WebGL in our app, but could not make it work (no errors though).
Is it possible that Overwolf does not support WebGL at the moment?

You can to add the enable_osr_acceleration flag to your app manifest file.

Note that this flag is still in Beta, so it might not work as expected.

BTW if you want to check if your window is accelerated, you can use isAccelreatedOSR().
