With the current release feature 1 can be achieved by ```js const areAllLayersLoaded = deck.props.layers.every(layer => layer.isLoaded); ``` Feature 2 can be achieved by ```js const {timeline} = deck.animationLoop; //...

Theoretically, no. A custom layer could implement `isLoaded` however it likes. In practice, all official layers calculate `isLoaded` from the status of aync fetches, and they all trigger update/redraw when...

I can see how the behavior is confusing in your case. According to the [documentation](https://deck.gl/docs/developer-guide/coordinate-systems#pixels): > When pixel sizes are viewed from a perspective (e.g. MapView with pitch, FirstPersonView or...

Thanks for the submission. If you test against the master branch (`yarn start-local`) you can use an externally constructed projection matrix: ```js onViewStateChange: ({viewState}) => { ... viewState.projectionMatrix = getProjectionMatrix(view);...

You can check which layer is picked with `pickInfo.layer`.

The errors seem to imply that there are other preceding errors? Are these all that you can see in the console? Are these devices able to load the example on...

Thank you for helping with the testing. Could you go to https://www.khronos.org/registry/webgl/sdk/tests/webgl-conformance-tests.html?version=2.0.1 on one of these devices and report the failed tests?

Thank you! Could you share the result from the following pages: - https://www.khronos.org/registry/webgl/sdk/tests/conformance2/extensions/ext-color-buffer-float.html?webglVersion=2&quiet=0&quick=1 - https://www.khronos.org/registry/webgl/sdk/tests/conformance/extensions/ext-float-blend.html?webglVersion=2&quiet=0&quick=1 - https://www.khronos.org/registry/webgl/sdk/tests/conformance/rendering/blending.html?webglVersion=2&quiet=0&quick=1

I do not have access to BrowserStack at the moment. Would you mind getting onto the [deck.gl Slack](https://github.com/visgl/deck.gl#learning-resources) so we can debug offline?

Update: looks like the Samsung devices report that they support the [EXT_float_blend](https://developer.mozilla.org/en-US/docs/Web/API/EXT_float_blend) extension but they throw when trying to actually render to a float target. This should definitely be reported...
