3D Mode: Invalid asm.js: Invalid member of stdlib #356

Closed Ysurac closed 6 years ago

Ysurac commented 6 years ago

Seems to be an error seen in Chrome/Chromium 61.x Issue open on Cesium: https://github.com/AnalyticalGraphicsInc/cesium/issues/5847

FWIW, this is apparently caused by Chrome now having that chrome://flags/#enable-asm-webassembly enabled by default.

Experimental Validate Asm.js and convert to WebAssembly when valid. Mac, Windows, Linux, Chrome OS, Android
Validate Asm.js when "use asm" is present and then convert to WebAssembly. #enable-asm-webassembly

Disabling it makes the message go away. Possibly because WASM doesn't have multithreading yet (or things related to it, I haven't really checked - maybe SharedArrayBuffer or Atomics...)

I found that out here randomly trying to understand (to no avail yet) why Chrome 62 is making my multi-threaded (2 threads) emulator very slow while it's working just fine on Chrome 61 and other latest browser versions...

Should be fixed since update to Cesium 1.40
